Question

Find the area of the circle. Diameter of a circle=5.2cm. Then what is the area of a circle?

Answer 1

The area of the circle is 21.2264.

Explanation:

Formula =
`\pi r^(2)`

We need to find out the radius which is half of the diameter.

Radius = 5.2 / 2 = 2.6cm

Next, we have to find 2.6cm to the power of two which is the same as saying 2.6 x 2.6.

2.6 x 2.6 = 6.76

Finally, we have to multiply it by
`\pi` to get the area of the circle.


`\pi` = 3.14

3.14 x 6.76 = 21.2264

Area = 21.2264

Answer 2

21.24cm
Radius is 2.6 and we know formula of a circle is pi times radius squared so radius squared is 6.76 and we multiply that by pi giving us 21.24cm
