Answer:
x = 9
Step-by-step explanation:
1/4(8x+12) =21
1/4 * 8x = 2x
1/4 * 12 = 3
2x + 3 = 21
21 - 3 = 18
2x = 18
18/2 = 9
x = 9
Given :-
Diameter of tank = 20 feet
Radius of tank, r = 20/2 = 10 feet
To Find :-
Volume of the hemisphere
Formula to be used :-
Volume of the hemisphere = 2/3 × π × r³
Solution :-
Putting the values, we get
Volume of the hemisphere = 2/3 × π × r³
⇒ Volume of the hemisphere = 2/3 × 22/7 × 10 × 10 × 10
⇒ Volume of the hemisphere = 44000/21
⇒ Volume of the hemisphere = 2095. 23 feet³
Now, Total weight of the water
⇒ Total weight of the water = 62.4 × 2095.23
⇒ Total weight of the water = 130742.35 pounds
Hence, the Total weight of the water is 130742.35 pounds
