Answer:
b. 1:4
Step-by-step explanation:
Area of cylinder A = πr²h = π(1.1).4 = 4π
Area of cylinder B = πr²h = π (2.2).4 = 16π
Ratio of their volumes = 4π/16π = 1/4 = 1:4
Answer: 77
Step-by-step explanation: Based on the order of operations or PEMDAS, parentheses are always done first.
So our first step in this problem is to simplify (9 + 2) to get 11.
So we now have (7) (11) which is 77.
Identify and calculate formulas and examples...

Answer:
1.375 seconds
Step-by-step explanation:
One mile is equivalent to 5280 feet. Throwing at 30 miles an hour is 0.5 miles each minute, or one mile every 120 seconds(Unfortunately for the pitcher, I don't think the ball would make it to home plate). That means it travels 1/120 miles each second, or 44 feet(5280/120). The ball will reach home plate in 1.375 seconds(60.5/44).
