The statement, "the lateral surface area of cone A is exactly half of that of cylinder B" is: A. True.
What is the Lateral Surface Area of a Cone and a Cylinder?
Lateral surface area of cone = πrl
Lateral surface area of cylinder = 2πrh
Lateral surface area of cone A = πrl = πrh
Lateral surface area of cylinder B = 2πrh
This means the lateral surface area of cylinder B is twice that of cone A. Thus, lateral surface area of cone A is exactly half of that of cylinder B.
The answer is: A. True.
