The circumference of a circle is 15π centimeters. what is the area of the circle in terms of π?

a. 7.5π cm²

b. 15π cm²

c. 56.25π cm²

d. 225π cm²

C.56.25π cm²

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

15 pi = 2 * pi *r

Divide each side by pi

15 = 2r

Divide by 2

15/2 = 2r/2

7.5 = r

We want to find the area

A = pi r^2

A = pi (7.5)^2

A = pi *56.25

A = 56.25 pi

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
