Question

1. what measurement do you need to calculate the volume of a cylinder?

a. radius
b. diameter
c. surface area
d. circumference

Explanation:

Step1: Recall the formula for the volume of a cylinder

The formula for the volume of a cylinder is \(V=\pi r^{2}h\), where \(r\) is the radius and \(h\) is the height.

Step2: Analyze each option

• Option a: Radius (\(r\)) is directly in the formula \(V = \pi r^{2}h\).
• Option b: Diameter (\(d = 2r\)), but we need \(r\) (since formula uses \(r^{2}\)), not \(d\) directly.
• Option c: Surface area is not part of the volume formula \(V=\pi r^{2}h\).
• Option d: Circumference (\(C = 2\pi r\)) is not part of the volume formula \(V=\pi r^{2}h\).

Answer:

A. Radius
