Question

The radius of a circle is 8 kilometers. What is the area?

Answer 1

Explanation:

`area \: of \: a \: circle = \pi * r^(2) \\ = \pi * 8 * 8 \\ = 201.061km ^(2)`

Answer 2

Area of the circle=
`200.96 km^2`

Explanation:

Area of a circle=
`\pi *r*r`

For radius(r)=8 km

The area of the circle is :

=
`\pi *8*8`

As:

`\pi =(22)/(7)=3.14`

Area of the circle:

`=3.14*8*8\\\\=3.14*64\\\\=200.96km^2`

The Area of the circle with the radius of
`8km` is
`200.96 km^2`
