Adrum of oil has a height of 4 ft and a radius of 1.2 ft. the oil cost $22 per ft³.

what is the cost to fill the drum of oil?

$397.9 is the answer, i took the test today

$397.90

First, we are going to find the volume of our drum of oil. Since a drum of oil is a cylinder, we are going to use the formula for the volume of a cylinder:

where

is the volume of the cylinder

is the radius of the cylinder

is the height of the cylinder

We know from our problem that the radius of the drum of oil is 1.2 ft and its height is 4 ft, so let's replace the values in our formula:

Now, we just need to multiply the volume of the drum of oil by the oil cost per :

Cost to fill the drum of oil =

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
