A right cylinder has a diameter of 40 mm and a height of 30 mm, as shown. Semester Test, Part 1 What is the volume of the cylinder?a. 37,680 mm3
b. 1256 mm3
c. 150,720 mm3
d. 12,000 mm3

Answers

Answer 1
Answer:

Answer: a. 37,680\ mm^3

Step-by-step explanation:

We know that the volume of a cylinder is given by :-

V=\pi r^2 h, where r is radius and h is height of the cylinder.

Given: The diameter of cylinder = 40 mm

The radius of cylinder =r=(40)/(2)=20\ mm

The height of cylinder = 30 mm

Then , the volume of the cylinder will be :-

V=(3.14) (20)^2 (30)=37680\ mm^3

Hence, the volume of the cylinder = V=37680\ mm^3
Answer 2
Answer: Volume = Area * height 
 = (pi/4)*D^2 * h
 = (pi/4)*(40)^2 * 30 
  = 37,680 mm3
so, the answer is (a)

Dr. Hunt just got his PhD, and he wants to print copies of his thesis in hardcover book format. He could use Wildgrove Printing, paying a setup fee of $38 and $6 for every book printed. Alternately, he could go through Salem University, paying an up-front fee of $36 and $7 per book. It turns out that, given the number of books Dr. Hunt wants to print, the two options cost the same amount. How many books is that? What is the amount?
