Question

Circle Q has a circumference of approximately 50 centimeters. What is the approximate length of the diameter, d? Use 3.14 for π. Round to the nearest tenth of a centimeter.

Answer 1

The correct answer is 15.9.

Answer 2

15.9 cm is the length of diameter.

Explanation:

It is given in the question a circle Q has a circumference = 50 centimeters.

We have to calculate the length of diameter of the circle.

Since circumference of the circle = 2πr = 50 cm

and we know 2r = diameter of the circle

d×π = 50

d = 50/π = 50/3.14 = 15.9 cm.

Therefore diameter of the circle Q is 15.9 cm.
