If the area of a circle measures 9/4 π cm 2, what is the circumference of the circle in terms of π?

Given that the area of the circle = .

Now question says to find the circumference of the circle.

Before finding circumference, we need to find the radius of the circle so let's use formula of area of circle which is :

plug the given value of area

take square root of both sides

Now we can use formula of circuference to find the circumference of given circle

Circumference

Circumference

Circumference

Circumference

Hence final answer is cm.

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
