Question

For a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. What size buttonhole is needed for a button with a circumference of 7.38 centimeters? (Use the value of 3.14 to represent pi.)

Answer 1

THE ANSWER IS 2.35 CM

Explanation:

Answer 2

Diameter is 2.36 cm.

Given:
Circumference = 7.38 cm

Circumference of a circle is computed by multiplying 2, pi, and its radius.

C = 2πr

7.38 = 2 (3.14) r
7.38 = 6.28r
7.38/6.28 = 6.28r/6.28
1.18 = radius

Diameter = 2r
Diameter = 2(1.18)
Diameter = 2.36 cm
