Question

3. What is the approximate volume of the sphere if the surface area is 482.8 mm²?

Answer 1

482 * (4/3) pi r^3
----------
4 pi r^2

Answer 2

Elaborate.

Answer 3

= 482.8 * r / 3

Answer 4

Take the SA equation solve for radius, plug radius into volume equation?

Answer 5

I dont get it...

Answer 6

first find r from surface area equation = 4 pi r^2 then
plug it into 482.8 * r / 3

Answer 7

\[SA = 4\pi r ^{2}\]

\[Volume= 4/3\pi r ^{3}\]

Answer 8

I already know the surface area...its 482.8...i dont know the radius

Answer 9

I dont know how to find the radius

Answer 10

SA/4(PI) = r^2 take the sqrt(SA/4(PI) = r.

Answer 11

thanks so much
