Question 1.
What is the formula for the Curved Surface Area of a hemisphere?
Show hintHide hint
Think about the surface area of a cylinder.
Question 2.
What is the radius if the CSA is 50π cm²?
Show hintHide hint
Use the CSA formula to solve for r.
3Question 3.
What is the formula for the volume of a hemisphere?
- (1/3)πr³
- (2/3)πr³
- 4/3πr³
Show hintHide hint
Recall that a hemisphere is half of a sphere.
4Question 4.
True or False: The Total Surface Area (TSA) of a hemisphere includes the area of the base.
- True
- False
Show hintHide hint
Think about what TSA means, it combines both areas.
Question 5.
A hemisphere has a curved surface area of 50π cm². Find the radius and total surface area.
Show hintHide hint
First find r using CSA, then use r to find TSA.
Question 6.
Given a hemisphere with a volume of 200 cm³, determine its radius and curved surface area.
Show hintHide hint
Calculate r from the volume and then apply it to find CSA.
