What is the volume of a cylinder of 8in by 0.5 ft in cubic inches
Naily [24]

The volume of cylinder is 1205.76 cubic inches

<em><u>Solution:</u></em>

We have to find the volume of cylinder

<em><u>The volume of cylinder is given by formula:</u></em>

V = \pi r^2h

Where "r" is the radius and "h" is the height of cylinder

<em><u>Given dimensions are:</u></em>

Radius = 8 inches

Height = 0.5 feet

<em><u>Convert feet to inches</u></em>

1 feet = 12 inches

Therefore,

0.5 feet = 12 x 0.5 = 6 inches

Thus, we have got,

height = 6 inches

<em><u>Substitute r = 8 inches and h = 6 inches in formula:</u></em>

V = 3.14 \times 8^2 \times 6\\\\V = 3.14 \times 64 \times 6\\\\V = 1205.76

Thus volume of cylinder is 1205.76 cubic inches

% decrease

The expression for the decrease

% decrease= (original-selling)/original *100

subsitute

% decrease= (180-63)/180 *100

Find the center and radius of circle and graph it <br><br> <img src="https://tex.z-dn.net/?f=%28x-4%29%5E%7B2%7D%20%2B%28%20y%20
sergeinik [125]

Answer:

centre = (4,-2)

radius = 3

Step-by-step explanation:

The centre-radius form of the circle equation is in the format

(x – h)² + (y – k)² = r²,

with the centre being at the point (h, k) and the radius being "r"

Given in the question an expression which can be write as

<h3> (x – 4)² + (y – (-2))² = 3²</h3>

So, by translating we can say that

centre = (4,-2)

and

radius = 3
