Question

If a circle has a Diameter of 4m and a Radius of 4 units. Then what is Circumference and Area of the circle?

Answer 1

Answer & Step-by-step explanation:

`Circumference=d\pi \\Area=r^2\pi`

The diameter of the circle is 8 m and the radius of the circle is 4 units. So, now we have to plug in the numbers so we can find the circumference and the area of the circle.

`Circumference=(8)\pi`

`Circumference=25.12`

So, the circumference of the circle is 25.12 m.

`Area=(4)^2\pi`

`Area=16\pi`

`Area=50.24`

So, the area of the circle is 50.24 units².
