Find the volume of a right circular cylinder with a height of 7 cm and a diameter of 18 cm. Use 3.14 for π. Include two decimal places.(1 point)
cm3
Volume of a cylinder = πr^2h
Since the diameter is 18 cm, the radius is half of that, which is 9 cm.
π = 3.14
r = 9 cm
h = 7 cm
Volume = 3.14 * 9^2 * 7
Volume = 3.14 * 81 * 7
Volume = 3.14 * 567
Volume = 1782.78
Therefore, the volume of the cylinder is 1782.78 cm3.
