The formula for volume of cylinder is V = \pi r^{2} h. So we fill in V = \pi 2^{2} 6. This will equal to 24\pi.

Volume of a cylinder can be calculated as:

V= πr²h

Values of r and h are given.
Radius = r = 2
Height = h = 6
π = 3.14

Using the values, we get:

V = 3.14(4)(6) = 75.36 cubic units

So, the answer to this question is 75.36

Find the diameter of a cone that has a volume of 56.52 cubic inches and a height of 6 inches. Use 3.14 for pi. a. 3 inches. b. 6
sergejj [24]
Volume of cone = (1/3)pi*r²h

56.52 = (1/3)*3.14*r²*6

56.52/(2*3.14) = r²

9 = r²

r² = 9

r = √9

r = 3

Diameter = 2*r = 2*3 = 6 inches.    b.

<u>Find total parts:</u>

3 + 5 = 8

-

<u>Find 1 part:</u>

5 parts = 140

1 part = 140 ÷ 5 = 28

-

<u>Find 8 parts (total):</u>

8 parts = 28 x 8 = 224

-

Given the vectors, a=3i+4j, b=-2i+5j, c=10i-j, d=-1/3i+5/2j, find -0.4a-0.3b+0.2d=?
sveta [45]

Answer:

-\frac{2}{3}i - \frac{13}{5}j

Step-by-step explanation:

-0.4(3i + 4i) - 0.3(-2i + 5j) + 0.2(-\frac{1}{3}i + \frac{5}{2}j)

-1.2i - 1.6j + 0.6i - 1.5j - \frac{0.2}{3}i + 0.5j

Converting to fraction form;

-\frac{6}{5}i + \frac{3}{5}i - \frac{1}{15}i - \frac{8}{5}j - \frac{3}{2}j + \frac{1}{2} j

<u>Solving the i part;</u>

\frac{-18i + 9i - i}{15} = -\frac{2}{3}i

<u>Solving the j part;</u>

\frac{-16j-15j+5j}{10} = -\frac{13}{5}j

So -0.4a - o.3b + 0.2d =  -\frac{2}{3}i - \frac{13}{5}j
