Question 546143: A trampoline has diameter of 10 feet what is it area
Answer by neatmath(302) (Show Source): You can put this solution on YOUR website!

We can assume that this is a round trampoline.

If the diameter is 10 feet, then the radius is half of that, or 5 feet.

Then we just need to use the Area of a Circle formula:

where pi is the value 3.1415926....

So we just need to substitute our value of 5 in for r:

feet squared is the EXACT answer, and we surely didn't need a calulator for this one.

However, a real world answer is probably more appropriate if you were trying to measure the area.

So we will use the value of 3.14 for pi to approximate the area:

So the area of our trampoline is about 78.5 feet squared.

I hope this helps! :)
