Question

What is the exact circumference of the circle? 101 it 201 ft 401 ft 600 ft

Answer 1

Given:

The diameter of a circle = 20 feet

To find:

The exact circumference of the circle.

Solution:

We know that the radius is half of the diameter of the circle.

The diameter of a circle is 20 feet. So, the radius of the circle is 10 feet.

The circumference of the circle is:

$C=2\pi r$

Where, r is the radius.

Substituting $\pi = 3.14, r=10$, we get

$C=2(3.14)(10)$

$C=(6.28)(10)$

$C=62.8$

Therefore, the exact circumference of the circle is 62.8 feet.

Note: All options are incorrect.
