Question

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

Answer 1

Answer:

r = 8 units

Step-by-step explanation:

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

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

Answer 2

Answer:

8 units

Step-by-step 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.
