Question

The circumference of a circle is 24 feet. What is the approximate length of the radius? Round to the nearest tenth​

Answer 1

given:

circumference= 24 feet

to find:

the radius of the circle.

solution:

$c = 2\pi \: r$

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

$r = \frac{24}{2 \times \pi}$

$r = 3.81972$

$r = 3.8 \: ft$

therefore, the radius of the circle is 3.8 feet.

Answer 2

Answer:

3.80

Step-by-step explanation:

The circumference has /pi and diameter

lets just say pi is 3.14

24/3.14 = 7.64

that means the diameter is 7.64

Radius is half, or 1/2 of the diameter

7.64/2 = 3.82

radius = 3.82

3.82 rounded is 3.8
