Answer:
1. R = 10 in C = 62.8 in
2. R = 13 ft C = 81.64 ft
3. D = 32 yards C = 100.48 yards
4. D = 24 cm C = 75.36 cm
5. D = 16 mm C = 50.24 mm
6. R = 7 in C = 43.96 in
7. R = 9 ft C = 56.52 ft
8. R = 20 yards C = 125.6 yards
9. D = 6 cm C = 18.84 cm
Explanation:
Radius = R Diameter = D Circumference = C pi = 3.14
R = D / 2
D = R x 2
C = 2 x pi x R or D x pi
I basically plugged in all the values into the formulas I gave above. If you need more help feel free to ask.
Hope it helps! (:
