Question

The circumference of a circle is 15.03

m. Find the radius and round to the
nearest hundredth.

Answer 1

2.39 meters

Explanation:

Given:

• Circumference = 15.03 meters

Circumference:

`\displaystyle \large{C=2\pi r}`

• C = circumference = 15.03
• r = radius

Therefore:

`\displaystyle \large{15.03=2\pi r}`

Divide both sides by 2π:

`\displaystyle \large{(15.03)/(2\pi)=(2\pi r)/(2\pi)}\\\displaystyle \large{2.3920... = r}`

Round to nearest hundredth:

`\displaystyle \large{r=2.39}`

Therefore, the radius is 2.39 meters
