Answer 1

Given:

• Diameter= 8ft

To find:

The circumference of the given circle.

Solution:

In order to find the circumference, first we'll have to find the raduis.

$d = 2r$

$\frac{8}{2}$

$= 4 \: ft$

Now, we can work out the volume.

$\huge\boxed{Fomula: C = 2\pi {r}}$

$c= 2 \times \pi \times 4$

$c = 25.13274 \: {ft}$

$\large\boxed{C = 25.13 \: ft\: (2 \: d.p)}$

Hence, the circumference of the given circle is 25.13 feets.
