Sierra is making a circular flower bed that has a diameter of 6 feet. She plans to put fresh soil in the flower bed before she plants any flowers. How many square feet of soil does she need?
Use 3.14 for pi.
Round your answer to the nearest square foot.
Step 1 - Radius = d i a m e t e r space divided by space 2
Step 2: Area = straight pi straight r squared
Step 1: Radius = diameter/2 = 6/2 = 3 feet
Step 2: Area = π * r^2 = 3.14 * 3^2 = 3.14 * 9 = 28.26 square feet
Rounded to the nearest square foot, Sierra needs approximately 28 square feet of soil.
