Question

The circumference of a circle is 60π cm. What is the radius of the circle

Answer 1

The radius of the circle is 30 cm. Option D is answer.

Step-by-step explanation:

We know the formula for the circumference of a circle:

C = 2πr

where:

C is the circumference

π is pi (approximately 3.14159)

r is the radius

We are given the circumference C = 60π cm. We can solve for the radius r by rearranging the formula:

r = C / (2π)

Plugging in the given value for C:

r = 60π cm / (2 * 3.14159)

r ≈ 30.12 cm

Rounding to the nearest whole centimeter, the radius of the circle is 30 cm.

Option D is answer.

Answer 2

15 cm

Step-by-step explanation:

Circumference of circle= 2πr, where r us the radius of the circle.

Given that the circumference of circle is 60πcm,

60π= 2πr

Divide by 2 on both sides,

15π= πr

Divide by π on both sides,

15= r

Thus, radius of circle= 15cm.
