Either enter an exact answer in terms of it or use 3.14 for it and enter your answer as a decimal.

Answer 1

12.568 unit

Explanation:

From the formular

`A=\pi r^(2)`

Answer 2

The area of the circle with radius 2 unit is 12.56 sq unit.

Explanation:

Given,

The radius of the circle is 2 unit

To find the area of the circle.

Formula

The area of a circle with radius r is π
`r^(2)` sq unit

For this sum we will take π = 3.14

So,

The area of the circle is = 3.14×
`2^(2)` sq unit

= 12.56 sq unit.
