Just do 3.14+3.14 times the height
Answer:
314.2in^2
Step-by-step explanation:
GIven data
diameter= 10in
radius= 5in
Height= 2in
The expression for the curved surface area (CSA) of a cylinder is given as
CSA=2πrh
CSA=2*3.142*5*2
CSA=62.84 in^2
The material needed to make one pipe is 62.84in^2
Hence the material need for 5 pipes is
=62.84*5
=314.2in^2
The amount in gallons of each milk containing 9% butterfat and milk containing 4% butterfat which must be used to obtain the desired 365 gallons are;
- 219 gallons of 9% fat.
- 146 gallons of 7% fat.
<h3>What quantity of each type of milk is required for the desired 365 gallon?</h3>
It follows from the task content that the quantity of each type of milk required to arrive at the targeted fat content and quantity of milk are to be determined.
Let x = quantity of 9% fat milk and
Let y = quantity of 4% fat milk
Therefore, by mass balance; we have;
x + y = 365.
Where; y = 365 - x.
Also, by fat balance; we have;
(9% × x) + (4% × y) = (7% × 365)
9x + 4y = 2555
Therefore, the two equations to be solved simultaneously by substituting y from the first equation into the second equation as follows;
9x + 4 (365 - x) = 2555
5x = 1095
x = 1095/5
x = 219 gallons.
Also, y = 365 - 219 = 146 gallons.

Step-by-step explanation:
Answer:
In the allocated budget of $130 , the business person can travel 462.55 miles a day.
Step-by-step explanation:
The daily rate of car service = $37.49
Cost per mile of the car = 20 cents = $ 0.20
Total allocated budget for each day = $130
Now, out of the total budget :
The actual travelling budget = Total Budget - Daily car rate
= $130 - $37.49
= $92.51
So, the actual travelling budget each day = $92.41
Now,
=
or, the number of miles traveled = 462.55 miles
Hence, in the allocated budget of $130 , the business person can travel 462.55 miles a day.
