The volume of a right circular cylinder is 29, 673 inches
. Find the diameter of the cylinder if the height
is 42 cm. Use 3.14 for n. (1 point)
• 10 inches
• 5 inches.
• 30 inches
• 15 inches
To find the diameter of the cylinder, we can use the following formula for the volume of a cylinder:
V = πr^2h
Given that the volume is 29,673 inches, the height is 42 cm, and π = 3.14, we can plug in the values and solve for the radius:
29,673 = 3.14 * r^2 * 42
29,673 = 131.88 * r^2
r^2 = 225
r = 15 inches
Since the diameter is twice the radius, the diameter of the cylinder is:
2 * 15 = 30 inches
Therefore, the diameter of the cylinder is 30 inches.
So, the correct answer is:
- 30 inches
