$40
40*90/100 = 36
You just have to be careful with the rest of the problem
Answer:
see explanation
Step-by-step explanation:
The circumference (C) is calculated as
C = πd ← d is the diameter
diameter = 2 × 9 = 18 in ( twice the top diameter ), thus
C = 18π in ← exact value ≈ 56.55 in ( to 2 dec. places )
(2,3) is your answer for the equation
The answer is 10 because its in the tens place
