Answer:
262 in
Step-by-step explanation:
the equation for volume of a sphere is : 
r
so replacing the number of the radius into the equation, it would look like:

r
which gives you 523.59878 in
but since it's a hemisphere, you'd divide it in half, which gives you 261.79939.
since you're rounding off to the nearest whole number, you're answer is 262 in
3 x 18 = $54
2 x 3.99 = $7.98
1 x 45.00 = $45.00
Add: $54 + 7.98 + 45 = $106.98
Multiply: $106.98 x 0.085 = 9.093
Add: $106.98 + $ 9.09 = $116.07
He paid $116.07 total.
