Question

What is the combined area of the two bases of the following cylinder?

Answer 1

Well, you have Diameter: so D/2 = R

Area of 1 base = pi*r^2, so area of 2 bases = 2*pi*r^2.

Answer 2

so that'd be 75.36?

Answer 3

@Geometrythebest, nope... It should be higher.

Answer 4

okay so the radius since its divided 12 by 2 =6? so then that's suppose to be r?

Answer 5

Yup, you got it.

Answer 6

ohh i see I forgot to multiply rxr :P wow thanks so much!
