The circumference of a circle is 16π cm. What is the area, in square centimeters? Express your answer in terms of \piπ.

Step-by-step explanation:

The area of a circle can be found using:

We have the circumference, but we need the radius. Circumference can be found using:

We know the circumference is 16, so we can substitute that in for c

16 =2 r

We need to solve for r, or the radius. To do this, divide both sides by 2. This will get r by itself.

16 /2 =2 r/2  

8=r

Now we know the radius, and can substitute it into the area formula

Substitute 8 in for r

This answer is expressed in terms of pi, since it includes pi in the answer. Therefore, the area, in terms of pi is

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
