Question

Can someone please help? I'm too dumbo to answer this on my own.​

Answer 1

d.
`√(3V\pi h )`/πh

Explanation:

isolating r

3* V = 3 *
`(1)/(3) \pi r^2h`

3V =
`\pi r^2h`

`(\pi r^2h)/(\pi h) = (3V)/(\pi h)`

`r^2 = (3V)/(\pi h)`

`√(r^2)= \sqrt{(3V)/(\pi h) }`

r =
`\sqrt{(3V)/(\pi h) }` =
`\sqrt{(3V)/(\pi h) }* (√(\pi h) )/(√(\pi h) )`=
`(√(3V\pi h ))/(\pi h)`
