What is the approximate circumference of a circle that has a radius of 63? Use 3.14 for π and express your answer to the hundredths place.

Answer 1

The circumference of a circle is given by the formula C = 2πr, where r is the radius.

Substituting the given value of radius, we get:

C = 2(3.14)(63) = 395.64

Rounding to the hundredths place, we get a circumference of 395.64.

Answer 2

What is the approximate circumference of a circle that has a diameter of 20? Use 3.14 for π and express your answer to the tenths place
