Question

Find the diameter and radius of a circle with the area of 29

Answer 1

The radius is

`√(29)`

The diameter is

`2 √(29)`

Explanation:

The area of the circle is represent as

`a = \pi * r {}^(2)`

Where r is the radius and a is the area. Since pi is a irrational number, we won't focus on doing nothing with that instead we just take the sqr root of both sides to find the r or radius.

`√(29)`

Which is the radius and it cant be simplified so the radius is

`√(29)`

The diameter is twice longer than the radius so we

`2 * √(29)`

Which is

`2 √(29)`

Answer 2

Diameter:6.08

Radius=D/2=6.08/2=3.04
