Show hintHide hint
Think about what area the CSA represents.
Question 2.
Can you briefly explain what the radius of a cylinder is?
Show hintHide hint
Look at the circular base of the cylinder.
3Question 3.
What is the formula for the Total Surface Area of a cylinder?
- 2πrh
- 2πr(h + r)
- πr²h
Show hintHide hint
Look for the formula that contains height and radius together.
4Question 4.
True or False: The volume of a cylinder is calculated by the formula: Volume = πr²h.
- True
- False
Show hintHide hint
Recall the formula for the enclosed space.
Question 5.
A cylindrical container has a radius of 3 cm and a height of 12 cm. Calculate the TSA and Volume, and then if you double the height, how much does the volume increase?
Show hintHide hint
Calculate the TSA and original volume, then use height to analyze changes.
Question 6.
If a cylinder is formed by taking a rectangular sheet of area 150 cm² and wrapping it while ensuring the height remains 5 cm, what would be the radius of the base?
Show hintHide hint
Start with your area formula and isolate to find radius.
