One, the top and the bottom of the trapezoid.
Answer:
The volume of the hemisphere is .
Step-by-step explanation:
We have,
The diameter of a hemisphere is 8 ft. It is required to find its volume.
The formula of the volume of hemisphere is given by :
r is radius of hemisphere
Here, r = 4 ft
So,
So, the volume of the hemisphere is .
6 - 2x = 0
- 2x = -6 *(-1)
2x = 6
x = 6/2
x = 3
S: {3}
