Question

A circle has a circumference of 50.24 units.

Answer 1

Answer:

8 units

Step-by-step explanation:

The circumference of a circle is given by

C = 2*pi*r

50.24 = 2 * pi * r

Using 3.14 to approximate pi

50.24 = 2 * 3.14 * r

50.24 = 6.28 r

Divide each side by 6.28

50.24/6.28 = r

8 = r

Answer 2

Answer:

radius = 8 units

Step-by-step explanation:

Circumference of a circle = 2πr

where

r is the radius

From the question

Circumference = 50.24 units

To find the radius substitute the value into the above formula and solve for the radius

That's

$50.24 = 2\pi \: r$

Divide both sides by 2π

We have

$r = \frac{50.24}{2\pi}$

r = 7.9959

We have the final answer as

radius = 8 units
