Question

A circular garden has a diameter of 6 feet. Which of the following is closest to the area of the garden?

Answer 1

The answer to this problem is 'B'.

This is because to find the area of a circle your formula is
A = 3.14•r²
So your first step is

1. Find the radius by dividing the diameter (6) by 2
6/2 = 3 Radius= 3

Now that you have found the radius (3) plug the number in the formula
2. A = 3.14•3²
OR
A = 3.14•3•3

Finally, solve the last step - Find the area
3.14 • 3 • 3 = 28.26
A = 28.26

Answer 2

The area for a circle is pir^2
If the diameter is 6 then the radius is 3 and if you square 3 you get 9, 9pi = B. 28.26 sq ft
