Question

The area of a circle is 16π m2. What is the radius of the circle?

Answer 1

Given the area
`A=\pi r^2=16\pi` we can solve the formula for radius.

`A=\pi r^2\Longrightarrow r=\sqrt{(A)/(\pi)}`

So,

`r=\sqrt{\frac{16\cdot\\ot{\pi}}{\\ot{\pi}}}=√(16)=4`

The radius is 4m.

Hope this helps.

Answer 2

the radius of the circle= 4m

Explanation:

Given:

Area of circle=16π m2

radius,r of circle=?

Formula of area of circle is given as

Area=πr^2

Putting values we get

16π=πr^2

r^2=16

r=4

the radius of the circle= 4m !
