Question

Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14 for π) the radius is 3

Answer 1

Area of the circle =
`28.26cm^2`

Explanation:

Radius of the circle= 3 cm

Area of the circle=
`\pi *r^2`

As,

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

Putting the values in the formula:

Area of the circle=
`3.14*3*3`

`=3.14*9\\\\=28.26cm^2`

The area of the circle is
`28.26cm^2`
