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

Answer»

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.
