Question

A trampoline has a diameter of 10ft. What is it’s area ?

Answer 1

78.54 square feet

Explanation:

The formula to find the area of a circle is πr², and since we know the diameter is 10 ft we know the radius is 5 feet, so π5²=78.54

Answer 2

Answer: 78.5 feet squared for short answer

Explanation:

If the diameter is 10 feet, then the radius is half of that, or 5 feet. 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 the area of our trampoline is about 78.5 feet squared.
