Question

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 a=2
`\pi` r (r+h) 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)/(2 \pi r)` 
b) h = 
`(a)/(2 \pi r)`
c) h = 
`(a)/(2 \pi r) - r^(2)`
d) h = 
`(a)/(2 \pi r) - r`

Answer 1

maybe is the answer C
