= - 1 ( cross- multiply )
- (2x - c ) = a ( distribute left side )
- 2x + c = a ( subtract c from both sides )
- 2x = a - c ( multiply both sides by - 1 )
2x = c - a ( divide both sides by 2 )
x =

Radius of hemisphere is 9.8 inches.
Step:1
Formula of volume of hemisphere is,
..................(1)
Where,
r - Radius of hemisphere
Step:2
From the given,
r = 9.8 inches
Equation (1) becomes,
=
=
= (0.66666666)(3.1415)(942.192)
= 1971.23
Volume of hemisphere = 1971.23 cubic inches
Result:is 1970.2 cubic inches.
