Answer:
12 inches
Step-by-step explanation:
Given data
Height= 11 inces
Volume= 4,973.76 cubic inches.
The expression for the volume of a cylinder is
V= πr^2h
substitute
4,973.76= 3.14*r^2*11
4,973.76= 34.54r^2
r^2= 4,973.76/ 34.54
r^2= 144
Square root both sides
r=√144
r=12 inches
Answer:
Selling price= $58.5
Step-by-step explanation:
Giving the following information:
Guitar cost price= $45
Mark up percentage= 30%
<u>To calculate the selling price of the guitar, we need to use the following formula:</u>

Selling price= 45* (1+0.3)
Selling price= 45*1.3
Selling price= $58.5
Answer:

Step-by-step explanation:
Answer: No. The intervals defined by the margin or error overlap
Step-by-step explanation:
If we think about it, with the worst margins, 55% could be 48% and then the 45% would be 52%, showing there is no clear yes or no and it is possible that the intervals could overlap
