35.75
explanation-
3.90 ph x 7.5 hours = 29. 25
plus the gas can 6.50
29.25+6.50= 35.75
7/100 = 0.07
0.07 * 12.5 = 0.88
20/100 = 0.2
0.2 * 12.5 = 2.5
2.5 + 0.88 = 3.38
3.38 + 12.50 = 15.88
You spend a total of $15.88.

Answer:
r = 
Step-by-step explanation:
A = πr-32
using algebraic manipulation to isolate r
A + 32 = πr-32 + 32
A + 32 = πr
(A+32)/π = πr/π
r =
