Question

A circle has a circumference of 50.2450.2450, point, 24 units. What is the radius?

Answer 1

8 units

Explanation:

Formula for the circumference of a circle

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

Solving for the radius

Let's substitute in the circumference, then solve for the radius.

`50.24 = 2\pi r`

50.24 ≈ 2(3.14)r

8 ≈ r

The answer

The radius is approximately 8 units.

Answer 2

r = 8 units

Explanation:

The circumference is calculated using
`C = 2\pi r`. Substitute C = 50.24 units. Solve for the radius.

`C = 2 \pi r\\50.24 = 2 \pi r\\25.12 = \pi r\\8 = r`
