Question

Find the missing part . Round to the nearest tenth.

Answer 1

10.6

Explanation:

The missing part is the radius of the circle.

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here A = 353, this

πr² = 353 ( divide both sides by π )

r² =
`(353)/(\pi )` ( take the square root of both sides )

r =
`\sqrt{(353)/(\pi ) }` ≈ 10.6 ( to the nearest tenth )
