Question

What is the area of a circle of radius (a) 5.142 m and (b) 1.7 m?

Answer 1

(a) Area =
`83.022m^2` (b) Area =
`9.07m^2`

Step-by-step explanation:

We have given radius of the circle r = 5.142 m and r = 1.7 m

We have to find the area of the circle

We know that area of the circle is given by

`A=\pi r^2`, here r is the radius of the circle

(a) Radius = 5.142 m

So area
`A=\pi r^2=3.14* 5.142^2=83.022m^2`

(b) Radius = 1.7 m

So area
`A=\pi r^2=3.14* 1.7^2=9.07m^2`
