Question
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
Answer
The radius of the cylinder is half of the diameter, so the radius is 18/2 = 9 cm.
The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height.
Plugging in the values, V = 3.14 * 9^2 * 7 = 3.14 * 81 * 7 = 3.14 * 567 = 1782.18
Therefore, the volume of the cylinder is 1782.18 cubic centimeters.
