If the circumference of a circle is 75 inches, the diameter is: about 23.87 inches. (diameter = circumference divided by pi).
The circumference equals the diameter times pi; therefore, the circumference of this circle is 24 X pi = 75 feet, to the justified number of significant digits (limited by "24").
The radius of a circle is half of its diameter. If the diameter of the circle is 150 cm, then the radius would be half of that, which is 75 cm. The radius is the distance from the center of the circle to any point on its circumference.
Well, honey, to find the circumference of a round pool, you use the formula C = πd. Since the diameter of a 24' round pool is 24 feet, you plug that in: C = π(24) = 75.4 feet. So, grab your measuring tape and get ready to walk around that pool about 75 feet to make sure you didn't skip leg day.
There are: pi*75 squared = 5625*pi square feet
