Question

If the radius is 15 and the diamiter is 30 whats the area?

Answer 1

area `=color(blue)(706.5 cm^2`

Explanation:

The area of a circle is given by formula
`color(blue)(pi(r)^2`

Where the radius is denoted by `r` and `pi` is a constant having value `3.14`

We have radius as `r = 15`

So area = `3.14 xx (15)^2`

`=color(blue)(706.5 cm^2`(assuming units to be in cm)
