Answer:
A=πr2=π·22≈12.56637cm²
the answer is 12.57cm squared.
Step-by-step explanation:
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
Step-by-step explanation:
Answer:
Length = 30.4 ft
Width = 3.6 ft
Step-by-step explanation:
Width: x
Length: 4x + 16
2(x) + 2 (4x + 16) = 68
2x + 8x + 32= 68
10x = 68 - 32
x = 36/10
x = 3.6
Width = 3.6 ft
Length: 30.4 ft
Answer: y = -2
Step-by-step explanation: Because the line is horizontal, the slope is 0. So on a graph the line will cut through (5,-2), (4,-2), (3,-2), (2,-2), (1,-2), and (0,-2). The line can pass through any x value, but the y value will always stay the same for this line. This means the y-intercept is -2. Because the slope is 0 and the y-intercept is -2, the equation is y = 0x -2, but there is no value in keeping the 0. So, you take it out leaving you with y = -2.
Hope This Helps! Good Luck and Have a Great Night!
