The circumference of a circle is 15π centimeters. What is the area of the circle in terms of π? A. 7.5π cm2

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

c

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
