Jack knows the surface area of a cylinder and its radius. He wants to find the cylinder's height. He needs to rewrite the formula to find the cylinder's height (h) in terms of the cylinder's surface area (A) and its radius (r). Which is the correct formula? A. h=r+A/2nr B. h=A/2nr C. h=A/2nr^-r^2 D. h=A/2nr^-r

Duncan Villarreal · Answer 1

h = A/πr²

Step-by-step explanation:

Surface area (A) of a cylinder = πr² * height (h), where r is the radius.

h = A : πr² = A/πr²
