Question

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

Answer 1

Answer:

Area of the circle=$200.96 km^2$

Step-by-step explanation:

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

For radius(r)=8 km

The area of the circle is :

                 =$\pi *8*8$

As:    

    $\pi =\frac{22}{7}=3.14$

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 $200.96 km^2$

Answer 2

Answer

Step-by-step explanation:

$area \: of \: a \: circle = \pi \times r^{2} \\ = \pi \times 8 \times 8 \\ = 201.061km ^{2}$
