The circumference of a circle is approximately 43.96 cm. What is the radius of the circle? Use 3.14

Question

A. 7 centimeters
B. 11 centimeters
C. 14 centimeters
D. 22 centimeters

Answer 1

We know that the formula for the circumference of a circle is C=2πr, where C is the circumference and r is the radius.

Substituting the given value for C and 3.14 for π, we get:

43.96 = 2(3.14)r

Dividing both sides by 2(3.14), we get:

r = 43.96/(2*3.14)

r ≈ 7

Therefore, the radius of the circle is approximately 7 centimeters.

Answer: A. 7 centimeters
