However, I'll solve on a general terms.
The volume of a hemisphere is: 
Take for instance

The volume becomes:

Answer:
x=(-2)
Step-by-step explanation:
subtract 4x from 2x
-6+7=1 4-2=2 subtract 1 from 2
-2x=1 x=-2
First, you would find the area of the rectangle using the formula A = L • W, which would then give you 24 cm2. Then you would find the area of the triangle using the formula A = bh1/2, which would the give you the answer of 8 cm2. Then you would have to find the area of the semi-circle, using the formula A = (r • r) • 3.14 / 2, which would then give you the answer of 25.12 cm2. Finally, you would have to add up all three area’s, so 25.12 + 8 + 24, which would then give you the final answer, which would be 57.12 cm2.
