Question

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

Answer 1

Answer:

the radius of the circle= 4m

Step-by-step 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 !

Answer 2

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

$A=\pi r^2\Longrightarrow r=\sqrt{\dfrac{A}{\pi}}$

So,

$r=\sqrt{\dfrac{16\cdot\not{\pi}}{\not{\pi}}}=\sqrt{16}=4$

The radius is 4m.

Hope this helps.
