The diameter of a hemispherical tank= 14 feet
Radius, r = 7 feet
water
Water weighs 62.4 pounds per cubic foot.
We need to find the total weight of the water in a full tank to the nearest pound.
The volume of the hemisphere is given by :

If water weighs 62.4 pounds per cubic foot, it means

.
Answer:
The side opposite angle C
Step-by-step explanation:
The angles of a triangle must add up to equal 180°. So 180=59+57+x
180=116+x
x=64°
In a triangle the smallest side is always opposite the smallest angle
