Step-by-step explanation:
Remember that the cone volume formula is 
, with r = radius and h = height. Using our information, we can form our equation as such: 
(I'll be keeping the answer in pi form.)
Firstly, solve the exponents:
Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3
C. $122.10
20 first hour
20+0.1*20 = 22 second hour
22+0.1*22 = 24.2 third hour
24.2+0.1*24.2 = 26.62 fourth hour
26.62+0.1*26.62 = 29.282 fifth hour
Total=$122.10
