Plsss hElpp!!!!! TY!!

Find the area of the circle below, to the nearest tenth. Use 3.14 for t.

Answer 1

Given:

A circle with diameter 9 cm.

To find:

The area of the circle.

Solution:

The area of a circle is:

`A=\pi r^2` ...(i)

Where r is the radius.

We know that, the diameter of a circle is twice than its radius.

The diameter of the given circle is 9 cm.

`r=(9)/(2)`

`r=4.5`

Substituting
`r=4.5, \pi =3.14` in (i), we get

`A=(3.14)(4.5)^2`

`A=(3.14)(20.25)`

`A=63.585`

`A\approx 63.6`

Therefore, the area of the given circle is 63.6.
