Question

What is the volume of a cylinder with a radius of 3inches and height of 6 inches

Answer 1

We are given,

• radius (r) = 3 inches
• height (h) = 6 inches

Solution,

• 
  `\sf \: Volume \: of \: cylinder = \pi {r}^(2) h`

Put the values;

`\sf \: Volume = (22)/(7) * 3 * 3 * 6`

`\sf \: Volume = (22)/(7) * 36`

`\sf \: Volume = (792)/(7) \approx113.14 \: {in}^(3)`

Answer 2

We have,

• Radius (r) = 3 inches
• Height (h) = 6 inches
• π = 22/7

Now,

`\tt \: Volume \: of \: cylinder = \pi {r}^(2) h`

`\tt \: Volume= (22)/(7) * {3}^(2) * 6`

`\tt \: Volume= (22)/(7) * 9 * 6`

`\tt \: Volume= (22)/(7) * 54`

`\tt \: Volume = (1188)/(7) \approx \: 169.71 \: {in}^(3)`
