20 total balls:
5 are black
17 NOT yellow
12 NOT green
20-17 = 3
20-12 = 8
5 Black + 3 yellow + 8 green = 16 balls
20 total balls - 16 balls = 4 blue balls
Ewa has 4 blue balls.
Circunference=pi times diameter
diameter=16in
circunfernce=16pi in
that is exact because pi is irrational
if we were to aprox pi to 3.14 hen
16 times 3.14=50.24
so answer is 16pi or 50.24 in
Answer:
17.85 feet.
Step-by-step explanation:
Area = 1/4 * 3.14 * r^2 where r is the radius
So r^2 = 19.625 / (1/4 * 3.14)
r^2 = 25
r = 5 feet.
The perimeter = 2r + 1/4 * 2* 3.14*r
= 2*5 + 7.85
= 17.85 feet.
