Question

if the surface area of hemisphere is s then express r in terms of s

Answer 1

Hey friend!

Here is your answer:

Let the surface area of a hemisphere be s

and radius = r

Then,

we know,

surface area of a hemisphere is 3πr²

⇒ s = 3πr²

⇒ r² = $\frac{s}{3\pi}$

⇒ r = $\sqrt{ \frac{s}{3\pi}}$

Answer: $\sqrt{ \frac{s}{3\pi}}$

I hope it helps you.
