Solve for the volume of the cylinder
9 cm height
3 cm width
Use 3.14 for π. Do not round.
Volume = πr²h
r = width/2 = 3 cm / 2 = 1.5 cm
h = 9 cm
Volume = 3.14 * (1.5 cm)² * 9 cm
Volume = 3.14 * 2.25 cm² * 9 cm
Volume = 3.14 * 20.25 cm³
Volume = 63.585 cm³
Therefore, the volume of the cylinder is 63.585 cm³.
Area of one circle base
To find the area of one circle base of the cylinder, we need to use the formula for the area of a circle, which is A = πr^2.
Given that the radius of the base of the cylinder is half of the width of the cylinder, we already calculated that the radius is 1.5 cm.
A = π(1.5 cm)^2
A = π(2.25) cm²
A = 2.25π cm²
Therefore, the area of one circle base of the cylinder is 2.25π cm².
