Answer 2

Explanation:

Circumference of a circle: C = 2*π*r

22/7 or π = 3.14

r (radius) = d/2

5. d/2 = 2

r = 10/2 = 5 cm.

C = 2*π*r

C = 2*3.14*5

C = 10*3.14

C = 31.4 cm.

6. r = 90 in.

C = 2*π*r

C = 2*3.14*90

C = 180*3.14

C = 565.2 in

7. r = 16 yd.

C = 2*π*r

C = 2*3.14*16

C = 32*3.14

C = 100.48 in

8. r = 4 in.

C = 2*π*r

C = 2*3.14*4

C = 8*3.14

C = 25.12 in.

9. d/2 = 2

r = 22/2 = 11 cm.

C = 2*π*r

C = 2*3.14*11

C = 22*3.14

C = 69.08 cm.

10. d/2 = 2

r = 4/2 = 2 m.

C = 2*π*r

C = 2*3.14*2

C = 4*3.14

C = 12.56 m.

11. In short words, a radius is half of its diameter. So a circle with a diameter of 8 cm has a radius of 4 cm because r = d/2. 8/2 = 4 cm.

Hope this helps!
