Question
The C.S.A. and T.S.A. of cylinder are in the ratio 1:2. If the T.S.A of the right cylinder is 616 sq. cm, then find its volume?
Hint:
CSA of a cylinder with base radius r and height h is and TSA is .
The correct answer is: The volume of the cylinder is 1078 cm3.
Explanations:
Step 1 of 4:
Given that CSA:TSA = 1:2
Step 2 of 4:
Similarly, CSA:TSA = 1:2
Step 3 of 4:
We have, CSA = 308
discarding the negative value since distance cannot be negative
Since , then cm
Step 4 of 4:
Volume of the cylinder = = cm3
Final Answer:
The volume of the cylinder is 1078 cm3.

A poster has an area of 432 square inches. The length , in inches, of the poster is 6 inches longer than the width of the poster. Which of the following equations can be solved to determine the length, in inches, of the poster?
Note:
The question can be further extended and ask us to find the length, breadth, or the perimeter of the poster. In that case, first we would solve the above equation to find the length of the poster and then use it to find the breadth. Finally we can find the perimeter easily by using the formula: perimeter (length + breadth).
