Answer:
circumference = 2 π r
r = 10/2 = 5inches
circumference = 2π ×5= 10π inches
option A
Volume of cylinder:
Formula: pi * r^2 * h
r = 2, h = 20
pi * 2^2 * 20
pi * 4 * 20 = 20pi
Solution: A
Ratio : 2:6:7....for a total of 15. This means that one side is 2/15 of the total perimeter, one side is 6/15 of the total perimeter and one side is 7/15 of the total perimeter.
and if the total perimeter is 45 inches...
2/15 * 45 = 90/15 = 6 inches
6/15 * 45 = 270/15 = 18 inches
7/15 * 45 = 315/15 = 21 inches
and the shortest side is gonna be 6 inches <==
