34.68 feet
• 3.32 feet
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.
Given that the area of the trampoline is 108.94 square feet, we can set up the equation as follows:
108.94 = πr^2
Now we need to solve for the radius (r). First, divide by π:
108.94 / π ≈ 34.64
Now take the square root to find the radius:
√34.64 ≈ 5.89
Therefore, the radius of the trampoline is approximately 5.89 feet. So the answer is:
• 5.89 feet
