Question

The cylinder below has a radius of 6cm and a volume of 550cm3. Work out the length of the cylinder. If your answer is a decimal give it to 2pm

Answer 1

The length of the cylinder is 4.87 cm.

----------------------

Volume of a cylinder formula:

• V = πr²h

We have the values:

• V = 550 cm³, r = 6 cm, π = 3.14

Find the missing length of h:

• 550 = 3.14*6²*h
• 550 = 113.04h
• h = 550/113.04
• h = 4.87 cm (rounded)
