(a)
Find the lateral area of the shade.
(a)
Answer to Problem 32PPS
Explanation of Solution
Given:
The lamp shade is a cylinder of height 18 inches with a diameter of
Formula Used:
The Lateral area L of a cylinder with radius r and height h :
Calculation:
diameter =
radius = r =
h = 18 inches
Lateral area of the shade =
(b)
Find the lateral area if the height is divided by 2.
(b)
Answer to Problem 32PPS
Lateral area becomes half.
Explanation of Solution
Calculation:
From part (a) , Lateral area =
Now, height becomes half of previous height
Lateral surface area now =
So, the lateral area becomes half of the original lateral area , if the original height is divided by 2 .
