Cylinder a has a radius of 7 inches and a height of 5 inches. cylinder b has a volume of 490n. what is the percent change in volume between cylinders a and b

step-by-step explanation:

given:

radius of cylinder a = 7 inches

height of cylinder a = 5 inches

volume of cylinder b = 490π

firstly we will find the volume of cylinder a.

apply the formula of volume of a cylinder.

v = πr²h

where r = radius

h = height

substitute the values of cylinder a to find the volume of cylinder a

v = π(7)² (5)

v= π 49 * 5

v = 245π

now find the ratio from b to a's volume:

volume of cylinder b/ volume of cylinder a

490π/245π

cancel the term by the table of 5.

98π/49π

now apply table of 7 to cancel out the terms:

=14/7

=2/1

it shows that cylinder b is 100% bigger than cylinder
