23. The standard trampoline has a diameter of 14 feet. What is its area?

To find the area of a standard trampoline with a diameter of 14 feet, first, you need to determine the radius. The radius is half the diameter, so it’s 7 feet. The area \(A\) of a circle is calculated using the formula \(A = \pi r^2\). Plugging in the radius, \(A = \pi (7^2) = 49\pi\) square feet. This gives you approximately 153.94 square feet! Perfect space for all those high-flying flips and jumps! Now, when you think about it, trampolines were originally made for training acrobats and military pilots back in the 1930s. Talk about a literal springboard into action! They’ve evolved into playground staples, providing a fun way to exercise while also encouraging coordination and balance. So next time you bounce, you’re joining a lineage of daredevil athletes!
