Formula for volume of a sphere: V = (4 / 3)(pi)(r^3)
Formula for circumference: C = (pi)(2r)
Solving for radius using circumference formula:
12 = (pi)(2r)
2r = 12 / pi
r = 12 / 2pi
Solving for volume:
V = (4 / 3)(pi)((12 / (2pi))^3)
Plug into calculator
V = 29.18 in^3
Hope this helps!! :)

Answer:
h = 13.333 +693.333/r
Step-by-step explanation:
For h hours, Brandee's pay will be ...
pay = 40r +(h -40)(1.5r) . . . . 40 hours at rate r + overtime (h-40) hours at 1.5r
pay = 40r +1.5hr -60r . . . . . eliminate parentheses
pay = 1.5hr -20r . . . . . . . . . . collect terms
Solving for h, we have ...
pay +20r = 1.5hr . . . . . . . . . . add 20r
h = (pay +20r)/(1.5r) . . . . . . . . divide by 1.5r
For the given pay of 800 +240 = 1040, we have ...
h = (1040 +20r)/(1.5r)
h = 13.333 +693.333/r . . . . . simplify to 2 terms

<em>Additional comments</em>
You need to know r to find the number of hours Brandee worked. She got paid $800 for a presumed 40-hours of regular time, so made r = $20 per hour. The above formula will tell you she worked 48 hours in the pay period.
Consider the following case:
Suppose a student earns $113.75 for painting and he works 13 hours, find his hourly rate.
In the above problem, to find the hourly rate, we need to divide the decimal 113.75 by 13.
The answer is:
