A cylinder has a height of 18 millimeters and a radius of 18 millimeters. What is its volume? Use ​ ≈ 3.14 and round your answer
solong [7]

Answer:

Volume = 18312.48

Step-by-step explanation:

Given

Height (h) = 18mm

Radius (r) = 18mm

Required

Determine the volume

The volume of a cylinder is calculated as thus:

Volume = \pi r^2h

Substitute values for r and h

Volume = 3.14 * 18^2 * 18

Volume = 18312.48

<em>Hence, the volume of the cylinder is 18312.48mm³</em>

maw [93]
<span>
Assign variables : 
Let x = first consecutive even 
Let x + 2 = second consecutive even
Let x + 4 = third consecutive even 
4x = 6 + 2(x+4) 
4x = 6 + 2x + 8 
4x = 2x + 14 
4x - 2x = 14 
so your answer is 7,9and 11</span>
