Write a program to calculate the surface area and volume of a square pyramid.
A square pyramid has a base that is square and all triangle faces are congruent isosceles triangles. (An isosceles triangle is a triangle in which two of the sides are equal.
Length of the base: a
Height of the pyramid: h
Volume = a2h/3
Slant height, s = sqrt(h2 + (a/2)2) This is the Pythagorean Theorem part.
Area of one pyramid side = s*a/2
Test Case #1 Height(h): 5.0’ Base(a): 2.5’
Write a program to calculate the surface area and volume of a square pyramid.
A square pyramid has a base that is square and all triangle faces are congruent isosceles triangles. (An isosceles triangle is a triangle in which two of the sides are equal.
Length of the base: a
Height of the pyramid: h
Volume = a2h/3
Slant height, s = sqrt(h2 + (a/2)2) This is the
Pythagorean Theorem part.
Area of one pyramid side = s*a/2
Here are my calculations:
Test Case #1 Height(h): 5.0’ Base(a): 2.5’
Volume = (2.5**2) * (5/3)
(6.25) * (1.66) = 10.375 cubic feet
Slant Height = math.sqrt(5**2) + (2.5/2)**2)
Sqrt(25+1.5625)
Sqrt(26.5625) = 5.154 feet
Pyramid (not including base) = (5.154) * (2.5/2) * 4
(5.154) * (1.25) * (4) = 25.769 sq. Ft.
I have attached a screenshot of my program I have so far. When I run the program, the output doesn't match what I have for the surface area and volume, am I missing something?
Write a program to calculate the surface area and volume of a square pyramid.
A square pyramid has a base that is square and all triangle faces are congruent isosceles triangles. (An isosceles triangle is a triangle in which two of the sides are equal.
Length of the base: a
Height of the pyramid: h
Volume = a2h/3
Slant height, s = sqrt(h2 + (a/2)2) This is the Pythagorean Theorem part.
Area of one pyramid side = s*a/2
For this program you are to determine two things about a square pyramid.
1) the surface area of the four sides. 2) the volume. Do not include surface area of the base.
Test case 1: Height: 5.0' Base: 2.5'
Test case 2: Height 2.5 Base: 4.3'
The program asks the user to enter the pyramid height (in feet) and length of the base (in feet). Your program will need to determine surface area, and volume by using pythagorean theorem. Your output should neatly show the height, base, total surface area, and volume of the pyramid using 33 decimal place of…

- write a program in python language: You are given a rectangular board of Mx N squares. Also you are given an unlimited number of standard domino pieces of 2 x1 squares. You are allowed to rotate the pieces. You are asked to place as many dominoes as possible on the board so as to meet the following conditions: 1. Each domino completely covers two squares. 2. No two dominoes overlap. 3. Each domino lies entirely inside the board. It is allowed to touch the edges of the board. Find the maximum number of dominoes, which can be placed under these restrictions. ex: 24 4arrow_forwardA fish-finder is a device used by anglers to find fish in a lake. If the fish-finder finds a fish, it will sound an alarm. It uses depth readings to determine whether to sound an alarm. For our purposes, the fish-finder will decide that a fish is swimming past if:there are four consecutive depth readings which form a strictly increasing sequence (such as 3 4 7 9) (which we will call "Fish Rising"), orthere are four consecutive depth readings which form a strictly decreasing sequence (such as 9 6 5 2) (which we will call "Fish Diving"), orthere are four consecutive depth readings which are identical (which we will call "Constant Depth").All other readings will be considered random noise or debris, which we will call "No Fish."Create a Python program called "fishfinder_firstname_lastname" that takes 1 input of string of 4 numbers separated with comma. Your program must display "Fish Rising", "Fish Diving.", "Fish At Constant Depth" or "No Fish".Example:30,10,20,20 Must display No…arrow_forwardPYTHON!!! A standard science experiment is to drop a ball and see how high it bounces. Once the “bounciness” of the ball has been determined, the ratio gives a bounciness index. For example, if a ball dropped from a height of 10 feet bounces 6 feet high, the index is 0.6, and the total distance traveled by the ball is 16 feet after one bounce. If the ball were to continue bouncing, the distance after two bounces would be 10 ft + 6 ft +6 ft + 3.6 ft = 25.6 ft. Note that the distance traveled for each successive bounce is the distance to the floor plus 0.6 of that distance as the ball comes back up. Write a program that lets the user enter the initial height from which the ball is dropped, the bounciness index, and the number of times the ball is allowed to continue bouncing. Output should be the total distance traveled by the ball. Below is an example of the program input and output: Enter the height from which the ball is dropped: 25 Enter the bounciness index of the ball: .5 Enter the…arrow_forward

Write a program to simulate the process and display the result.arrow_forwardUsing Dart. Create a program that will play the “cows and bulls” game with the user. The game works like this: Randomly generate a 4-digit number. Ask the user to guess a 4-digit number. For every digit the user guessed correctly in the correct place, they have a “cow”. For every digit the user guessed correctly in the wrong place is a “bull.” Every time the user makes a guess, tell them how many “cows” and “bulls” they have. Once the user guesses the correct number, the game is over. Keep track of the number of guesses the user makes throughout the game and tell the user at the end.arrow_forward
