Answer for the question:
3. An M-rated self-priming centrifugal pump will be used to dewater an excavation during construction. The required pumping volume is estimated at 250 gal/min. The pump will be located 10 ft above the bottom of the excavation. The suction line will consist of 20 ft of 3-in hose, and the discharge line will consist of 80 ft of 3-in hose. Water will be discharged 30 ft above pump level. What is the total head developed"

Step-by-step explanation:
An expression is a <u>set of terms that are combined using addition, subtraction, multiplication, or division.</u> The following are examples of expressions:
Note: expressions do not equal anything.
In contrast, equations are <u>expressions that equal at least one term.</u> The following are examples of equations:
Note: equations <u>do</u> equal a term, as shown in the examples.
The surface are of the right cone is 176 sq.units. Option A) is the correct answer.
<u>Step-by-step explanation</u>:
<u>step 1</u> :
Radius of the cone, <em>r = 4</em>
Height or length of the cone,<em> h = 10</em>
<u>step 2</u> :
Total surface area of right cone = πrh + πr^2
= (π4
10) + ( π
4^2)
= 40π + 16π
= 56 π = 563.14
= 176 sq.units
