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

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
