Find the volume of the cylinder. What is the exact volume in terms of π? (diameter= 16m) Options a.) 1000pi cubic m b.) 1024pi c

Kazeer [188]

The volume for any cylinder, right or oblique, would be base x height. Even though an oblique cylinder looks quite different from a right cylinder, their volumes would be equal (given that their radius and height are equal). Think about it, the area of a parallelogram would equal the area of the rectangle if their heights and bases were the same, so that would apply for this also.

V= Bh
The base would stand for that top and bottom of the cylinder, or the circles. The volume for circle is pi x radius squared.
V = $\pi r^{2}$ h
V = $\pi$ 256 x 16
V = $\pi$ 4096 $m^{3}$

A book sold 39,300 copies in its first month of release. Suppose this represents 6.1% of the number of copies sold to date. How

alexdok [17]

Answer:

644,262 copies

Step-by-step explanation:

Since this is a proportion problem, and we are given three values and one variable which is the total number of copies sold to date (x). Then we can use the Rule of Three to solve this problem. To do this we simply multiply the diagonal values and divide by the last value which would give us the value of the variable x

39,300 copies <======> 6.1%

x copies <=======> 100%

(100*39,300) / 6.1 = 644,262 copies

Therefore, a total of 644,262 copies have been sold to date.
