Question

Here is a graph of the relationship between the height and volume of some cylinders that all have the same radius, R. An equation that represents this relationship is V =Rºh (use 3.14.as an approximation for 7). What is the radius of these cylinders?​

Answer 1

• Radius is 1 unit

Explanation:

The relationship is:

• V = πr²h

We have points on the graph:

• (9, 28.26) and (18, 56.52)

Use one of the points, substitute into equation and solve for r:

• 28.26 = 3.14*9*r²
• r² = 28.26/28.26
• r² = 1
• r = 1
