Question

What is the difference between the areas of a circular table with diameter 6ft and a circular table with diameter 8 ft ? Round your answer to the nearest square foot

Answer 1

22 square feet

Explanation:

To find the area of a circle, you need to multiply pi times the radius squared. For the circular table with a diameter of eight, the radius is 4. When you square 4 and multiply it by pi, you will find that the area is approximately 50.27 square feet.

As for the area of the circular table with a diameter of 6, you can use the same strategy. The radius is half of the diameter, so 3. 3 squared times pi is approximately 28.27 square feet.

Then to find the difference you need to subtract the first area you found by the second are you found.

50.27 - 28.27 = 22 square feet

Answer 2

22 ft^2

Explanation:

The area of a table with diameter 6 ft

A = pi r^2 = pi (6/2) ^2 = pi 3^2 = 9pi

The area of a table with diameter 8 ft

A = pi r^2 = pi (8/2) ^2 = pi 4^2 = 16pi

Subtract 16pi-9pi = 7pi

Using 3.14 for pi

7 * 3.14

21.98 ft^2

To the nearest square foot

22 ft^2
