Question

find the surface area of in terms of PI
A ball has the diamiter of 24

Answer 1

ok, use the formula that i gave it to you. But remember it's radius in the formula. so you have to convert the diameter to radius.

In a diameter, there are 2 radius. Thus, divivde the diameter/2 to get radius.

And plug in the information you have into this formula, Surface Area = 4(pi)r^2

Hope you get it... =)

Answer 2

so it would be 601 ?

Answer 3

no 616!

Answer 4

Nope, it's 4(pi)r^2 = 4(pi)(24/2)^2 = 4(144)(pi) = 576 pi

Answer 5

oh now i see why...i forgot a step!
