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

Step-by-step explanation:
The first one: whole equation when move1 to the left, same with the second I believe
Answer:
The unit rate in miles per hour = <em>1.4 miles/hr</em>
Step-by-step explanation:
Given that:
Distance walked by Boardman family = Two over five of a mile = 
Time taken by Boardman family = Two over seven of an hour = 
To find:
The unit rate in the miles per hour = ?
Solution:
Formula for the rate or the speed can be given as:
Putting the values:
So, the unit rate in miles per hour = <em>1.4 miles/hr</em>
Answer:
The correct answer is:
A. 27,465 +52,534 = 79,899
Step-by-step explanation:
Given are the options for addition
We have to check each addition one by one
So,
A. 27,465 +52,534 = 79,899
This option is the example of error of addition by one. The answer should have been 79,999. Hence there is an error in addition ..
Hence, option a: 27,465 +52,534 = 79,899 is the correct answer ..
