So the amount needed=area of circle times height
area formula=pi times radius^2
height=3/4
so
pi=aprox 3.14
radius=7
3.14 times 7^2
3.14 times 49
153.86
times 3/4
115.395 in^3
answer is 115.4 cubic inches
Answer: 178.1

Step-by-step explanation:
A manufacturer of hair care products tested a new shampoo on 5,000 people, and 0.3 percent of the participants experienced a moderate allergic response. 15 of the 5,000 individuals experienced a minor allergic response.
<h3>Define percentage.</h3>
The easiest approach to utilizing percentages is to compare two numbers while setting the second amount's base to 100. Consider for a moment that we are interested in the proportion of working women. A percentage (%) is a number that represents how many out of 100 it is and may also be written as a decimal or fraction. To convert a percentage to a fraction, place the percentage's value in the numerator and 100 in the denominator.
Given,
15 of the 5,000 individuals experienced a minor allergic response.
Dividing the percentage of the population that had a minor reaction.
15 ÷ 5000
0.003
Multiplying it by 100 for percentage:
0.003 × 100%
0.3%
0.3% percent of the people had mild allergic reactions.
