Question

A cylinder has a height of 5.3 cm and a diameter of 3.0 cm. What is its volume? (Hint: Volume of a cylinder = r2h )

25.0 cm3
66.2 cm3
149.9 cm3
37.5 cm3

Answer 1

can be rounded to 37.5, which means the answer is 37.5 cm^3.

Step-by-step explanation:

Answer 2

The volume of a cylinder is πr^2h
Diameter is 2 times the radius.
This can be simplified to 3.14(1.5^2)(5.3)
This is because the radius is 1.5, which is half of 3, the diameter.
Now just solve:
1.5^2 = 2.25
3.14•2.25 = 7.065
7.065•5.3 = 37.4445
This can be rounded to 37.5, which means the answer is 37.5 cm^3.
