Lawrence has planted a round flower garden in his back yard. The garden is 8 feet across.
How many feet of fencing does Lawrence need to enclose the flower garden?
C = 3.14 * 8
C = ?
Thank you
You're welcome.
To find out how many feet of fencing Lawrence needs to enclose the flower garden, we need to calculate the perimeter (P) of the garden.
The formula for the perimeter of a rectangle is P = 2l + 2w, where l is the length and w is the width.
However, since Lawrence has a round flower garden, we can use the formula for the circumference (C) of a circle, which is C = πd (where π is approximately 3.14 and d is the diameter of the circle).
In this case, the diameter (d) of the garden is 8 feet, so we can plug it into the formula for circumference:
C = 3.14 * 8
C ≈ 25.12 feet
Therefore, Lawrence needs approximately 25.12 feet of fencing to enclose the flower garden.
