Question:
A reservoir in the shape of a right circular cylinder has a height of 84ft. If it to contain 79,200 L of water, find its radius.
Answer:

Step-by-step explanation:
Given
---- V
--- h
Required
Determine the radius

Convert volume to 


The volume (V) of a cylinder is:

Substitute values for volume and height

Divide both sides by 84

Take
as 3.14

Divide both sides by 3.14


Take the square root of both sides


<em>Hence, the radius is 3.26 ft</em>
Answer=I
15(x+3)+11x represents the total cost
To solve for this, let's look at the information that we know...
26 students go on the trip
15 students pay $3 more for an additional class (x+3)
26-15=11
11students pay, x, the price of the trip.
So 15(x+3) represents the 15 students who pay for both the trip and the automotive class, and 11x represents the students who simply just pay for the cost of the trip.
Thus, 15(x+3)+11x represents the scenario
Answer:
B i think
Step-by-step explanation:
you are supposed to multiply the 80*.3 and that will give you 24 and subtract from 80 but im not sure
sorry if i got this wrong
