Answer:

The radius of the circle is 4.7 in

Step-by-step explanation:

To solve this problem we have to use the circumference formula

c = circumference = 29.5in

r  radius

π = 3.14

c = π * 2r

we replace with the known values

29.5 in= 3.14 *  2 * r

29.5 in / (3.14 * 2)

29.5 in / (6.28)

4.69745 in

round to the nearest tenth

4.69745 in = 4.7 in

The radius of the circle is 4.7 in
