Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
Question
![**Problem 4: Find the Surface Area of a Cone**
A diagram of a cone is provided with the following dimensions:
- Radius (r) = 8 meters
- Slant height (l) = 15 meters
To find the surface area (A) of a cone, use the formula:
\[ A = \pi r (r + l) \]
Given options for the surface area are:
- \( 200\pi \, \text{m}^2 \)
- \( 320\pi \, \text{m}^2 \)
- \( 120\pi \, \text{m}^2 \)
- \( 184\pi \, \text{m}^2 \)
The correct choice can be found by calculating the surface area using the provided formula and dimensions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4e38067e-40f1-4c9f-beaa-f39c1c774668%2Fbaf9c7c4-e42b-43e1-9500-b70a3f4980a8%2F16spp2v_processed.png&w=3840&q=75)
