Answer:
Step-by-step explanation:
The formula for volume of a cylinder is
V = πr²h where r is the radius and h is the height.
We are given r = 5 and h = 2.5, plug those values in and simplify...
V = π(5²)(2.5)
V = π(25)(2.5)
V = 62.5π
Answer:
14
Step-by-step explanation:
7/5. = x/ x- 4 (the ratio to each other is the same)
cross multiply
7x-28 = 5x
simplified: -2x = -28
divide x and -28 by -2
x= 14
x= # of girls
