Question 1.
Calculate the volume of a cylindrical tank with a radius of 2m and height of 4m.
Show hintHide hint
Use the volume formula V = πr²h.
Question 2.
What is the surface area of the same tank?
Show hintHide hint
Remember the surface area formula SA = 2πr(r + h).
3Question 3.
What is the formula for the volume of a cylinder?
- V = πr²h
- SA = 2πr²
- V = 3πr
Show hintHide hint
Consider the base area times height.
4Question 4.
True or False: Surface area is important for finding how much material is needed to cover a shape.
- True
- False
Show hintHide hint
Relate the concept to real-world applications.
Question 5.
A water tank is designed to hold 10,000 liters. If the tank is cylindrical with a height of 5m, find the radius.
Show hintHide hint
Rearrange the volume formula to isolate the radius.
Question 6.
Estimate how much paint is required to cover both cylindrical and circular ends of a tank with radius 3m and height 4m if 1 liter covers 10 m².
Show hintHide hint
Don't forget to consider both the lateral surface and the ends.
