Answer:
60
Step-by-step explanation:
Set up a ratio problem
15/25 = 36/x
15x = 900
x = 60
Total of $7.75
13 more quarters than nickels
15 nickels = $0.75
28 quarters = $7.00
28 - 15 = 13 coins

Answer:
104 yd^2.
Step-by-step explanation:
Area of the 2 circles = 2 * π r^2
= 2 * π * 4^2
= 32 π yd^2.
Area of the side of the cylinder = 2 π r h
= 2 π * 4 * 9
= 72 π yd^2.
Total surface area = 32 + 72
= 104 yd^2.
