Question

Estimate the circumference of a circle that has a radius of 11 m simplify it.

Answer 1

ANSWER

$C=22\pi \: m$

EXPLANATION

The circumference of a circle is calculated using the formula:

$C=2\pi \: r$

where r=11 meters is the radius of the circle.

Let us substitute the radius into the formula to obtain,

$C=2\pi \: \times 11$

This simplifies to:

$C=22\pi$

When we substitute

$\pi = 3.14$

We get

$C=22(3.14) = 69.08m$

to the nearest hundredth.
