To find the area of the circular surface of the trampoline, you can use the formula for the area of a circle, which is A = πr^2, where r is the radius of the circle.
1. Given that the diameter of the circle is 12 feet, the radius (r) is half of the diameter, so r = 12/2 = 6 feet.
2. Now, substitute the radius (6 feet) into the formula to find the area:
A = π * (6)^2
A = π * 36
A ≈ 113 square feet
Therefore, the area of the circular surface of the trampoline is approximately 113 square feet when rounded to the nearest whole number.
