Question

Which circles have an area of 36pi ft2?

Choose all answers that are correct.

A.
a circle with a radius of 6 ft

B.
a circle with a diameter of 6 ft

C.
a circle with a radius of 12 ft

D.
a circle with a diameter of 12 ft

Answer 1

A.
a circle with a radius of 6 ft

D.
a circle with a diameter of 12 ft

This pi is a constant value expressed by the quotient of its circumference over the diameter. What type of number best describes the diameter is the pi. Hence, if we describe the diameter, diameter is the quotient of pi over the circumference of a circle by itself. It can’t change in value since for every solution and quotient of a circle each calculation gets 3.14 more or less.
