Step-by-step explanation:
V= π r^2h

Pi
First you need the radius, if the diameter is 10inches divide by 2 = 5 inches, that's your radius.
π(5inches)^2 times (20 inches)
firsr work out 5^2= 5x5= 25
π(25inches) times (20inches)
25x20=500π inches
500π =1,570.7963267948966192313216916397514420985
which rounds to 1,570, the first one is your answer
Answer:
22
|-15 - 7|
-15 - 7 = -22
|-22| = 22
(12+10+x)/3=15
15*3=12+10+x
45-12-20=x
X=23
