Question

A can in the shape of a right cylinder is filled with 10W-40 oil. The weight of 10W-40 oil is 0.857 gram per cubic centimeter. If the cylinder has a radius of length 6 cm and a height of 10 cm, calculate the weight of the oil (in grams) in the can.

Answer 1

First find the area of the cylinder using the following formula 
$A = 2\pi rh + 2\pi r^2$
$A = (2 \times \pi \times 6 \times 10) + (2 \times \pi \times 6^2)$

After finding the area, calculate the weight of the oil (in grams) in the can

weight in grams = A times 0.857
