A hemispherical tank is filled with water and has a diameter of 12 feet. If water weighs 62.4 pounds per cubic foot, what is the
1 answer:
Answer:
The total weight = 1286 × 62.4 = 80246 pounds.
Step-by-step explanation:
The formula of the volume of the sphere is
V = 4/3×π×r³
Given
d = 17 feet
d = 2r
r = d/2 = 17/2 = 8.5 feet
V = 4/3×π×r³
Since we need half of the volume as it is a hemispherical tank.
= 1286 ft³
Given that the weighs 62.4 pounds per cubic foot
Thus, the total weight = 1286 × 62.4 = 80246 pounds.

Step-by-step explanation:
To find the midpoint, simply use the Midpoint Formula.
The Midpoint Formula states that for two points and
, the midpoint will be:
.
So, here, = (-2, -1) and
= (-2, 4). The midpoint is then:
Thus, the answer is .
