Cylinder a has a radius of 1 m and a height of 4 m cylinder b has a radius of 1 m and a height of 8 m what is the ratio of the volume of cylinder a to the volume of cylinder b

a. 1: 2
b. 2: 1
c. 1: 1
d. 1: 4

option a

Step-by-step explanation:

The volume of a cylinder can be calculated with this formula:

Where the radius is "r" and the height is "h"

Calculate the volume of the Cylinder A:

Calculate the volume of the Cylinder B:

Now, the ratio of the volume of the Cylinder A to the volume of the Cylinder B can be calculated with:

Substituting values, you get:

or 1:2

a

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
