An oil filter for a small car is cylindrical its a diameter = 3.6 inches
Here diameter = 2* radius
Divide each side by 2
diameter / 2  = radius
There fore radius = diameter / 2
Substitute diameter = 3.6 inches
radius (r) = 3.6 / 2
r = 1.8 inches
An oil filter for a small car is cylindrical its a radius = 1.8 inches
 The cylinder height (h)  = 3.6 inches
The volume of the cylinder =π * r2 * h
Substitute π = 3.14(approximately) , r = 1.8 inches and h = 3.6 inches
There fore The volume of the cylinder = 3.14 * 1.82 * 3.6
The volume of the cylinder = 41.14656
The volume of the oil filter = 41.15cube inches.(Nearest round the ten digits)

Volume of the oil filter V = 3.14 * 1.82 * 3.6

V = 36.62 cube inches.
