Answer: 294cm
Step-by-step explanation:
The volume of a oblique cylinder is given by:
Volume= πr^2h
where
π = 3.14
r = radius
h = height
Radius= diameter/2 = 6/2 = 3
We have all the values, so we put it in the formulae so we can get the answer.
Volume= πr^2h
= 3.14 × 3 × 3 × (0.4 × 26)
= 294cm
100%=80cars
1%=0.8cars
35%=28cars
80-28-16=36 tan cars
36/80 x 100% =45%
