Circle P has a circumference of approximately 75 inches. what is the approximate length of the radius, r? use 3.24 for pi. round to the nearest inch.

Answer:11.9 inches

Step-by-step explanation:

Circumference (c) = 75inches

Pi=3.14

Circumference (c) = 2 x π x radius (r)

75=2 x 3.14 x r

75=6.28 x r

Divide both sides by 6.28

75 ➗ 6.28 = (6.28 x r) ➗ 6.28

11.9=r

Therefore radius=11.9 inches

1) 12in

Step-by-step explanation:

The circumference is 75, so to find the diameter you have to divide 75 by 3.14. You get 24 approximately. Then divide the diameter by 2, so 24/2=12.

Your error: pi is 3.14 not 3.24
