Kent has two similar cylindrical pipes, pipe a and pipe b. the radius of pipe a is 6 cm, and the radius of pipe b is 2 cm. what
White raven [17]

The ratio of the volume of pipe a to the volume of pipe b is 27:1  .

<h3>What is cylinder?</h3>

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder.

Given that,

Radius of pipe a is 6 cm, and the radius of pipe b is 2 cm.

We know that the volume of cylinder is :- \pi r^{2}h

where r is radius and h is height of the cylinder.

If two figures are similar then ratio of volume is equal to the cube of any dimension.

The ratio of the volume of Pipe a to the volume of Pipe b  :-

\frac{V(a)}{V(b)}=\frac{6^{3} }{2^{3} }

       = \frac{27}{1}

Hence, The ratio of the volume of pipe a to the volume of pipe b is 27:1 .

Evaluate this expression <br> (-7--9)*(8+2)
Marizza181 [45]
Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.

P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction

Knowing this, we should start by doing the equations <em>within </em>each parentheses.
 
(-7 - -9) *(8 + 2)
 (2) *(10)

So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

(2)*(10) = 20

20 is the answer.
