Question

How to find surface area in pi

Answer 1

(2πr * h) + 2(πr^2) for cylinder, πr^2 + πrl for cone, and πr^2 + πrl for a sphere.

Explanation:

Keep in mind:

r = radius

h = height

l = slant height

To find the surface area of a cylinder:

(Circumference * height) + 2(base which is a circle)

(2πr * h) + 2(πr^2)

To find the surface area of a cone:

Base(which is a circle) + π(radius)(slant height)

πr^2 + πrl

To find the surface area of a sphere:

4πr^2

Answer 2

Answer: How Do You Find Surface Area in PI?

Explanation:

Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. It doesn't have a surface area. However, the area of a circle is pi times the radius squared (A = π r²).
