Question

3. Find the volume of the cylinder

4. Find the volume of a cylinder with a diameter of 16mm and a height of 5.7 mm.

Answer 1

Diameter=16mm, so the radius is 8. The formula for volume of a cylinder is the area of the base times height, or v=πr²h.
Substituting the values in, we get π(8²)(5.7), which gives us roughly 1146mm^3.

Answer 2

`3)~v=8491mm^3`

Explanation:

3) volume of cylinder is...

v= πr²h

plug r= 13 and h=16

• v=π(13)²(16)
• v=π(13×13)(16)
• v=π(169)(16) ← plug π=3.14
• v=3.14(2704)
• v=8490.56
• v=8491mm^3

so, your answer is B
