The diameter of a circular swimming pool is 10 feet. Find its circumference. Round to the nearest tenth.
Use 3.14 for it.
d = 10 ft.

answer

31.4 ft squared

explanation

the circumference of a circle is c = 2r * pi = d * pi

plug in 10 for d (diameter) and 3.14 for pi

c = 10 * 3.14

c = 31.4 ft squared

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
