Question

Area of circle with radius of 2

Answer 1

`4\pi` or 12.56

Explanation:

`\pi r^(2)` is the formula to find the area of a circle.

if we plug '2' in...
`\pi2^(2)`

which equals to
`4\pi`

if we multiply 4 with pi, it equals to 12.56

Answer 2

Area of circle = 12.56 sq. units

Explanation:

radius = 2

Area of circle = π r² sq. units

= 3.14 * 2 * 2 = 12.56 sq. units
