What is the approximate length of the radius, /? Use 3.14
for . Round to the nearest inch.
O
O
O
12 inches
24 inches

Answer 1

5 inches.

Explanation:

We know that the circumference of a circle is equivalent to πr² or πd.

We need to know the radius given the circumference.

C = πr²

75 = 3.14(r^2) (Divide both sides by 3.14)

23.88535031847134 = r^2 (Take the square root of both sides)

r ≈ 4.88726409338

r ≈ 5 inches.
