Amanda's family has a swimming pool that is 4 feet deep in their backyard. if the diameter is nearly 25 feet, what is the circumference of the pool?
express your answer to the nearest whole foot.

79 ft

Step-by-step explanation:

The formula for the circumference of a circle is

C = 2πr.  If it's the diameter that is known, then C = πd.  We will use the latter formula to find the circumference of this pool:

C = π(25 ft) = 78.54 ft, approx., which, to the nearest foot, is 79 ft

45.3592

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
