Answer:

Radius = 4.7 in

Explanation:

To find the radius of the circle with a circumference of 29.5 in, we will follow the steps below;

First, lets write down the formula of the circumference of a circle.

The circumference of a circle is given by C = 2πr

where c = circumference of the circle and r = radius of the circle.

From the question given, circumference C = 29.5 and π = 3.14

Lets insert the values into the formula

C = 2πr

29.5 = 2× 3.14×r

29.5 =6.28r

Divide both-side of the equation by 6.28

29.5/6.28 =6.28r/6.26

On the right-hand side of the equation 6.28 will cancel-out 6.28 leav ing us with just r while on the left-hand side of gthe equation 29.5 will be divided by 6.28

4.7 ≈ r

r≈4.7 in to the nearest tenth

Radius = 4.7 in
