NEED HELP ASAP PLEASE WILL GIVE BRAINLIEST:

Three different cones are used for the storage of food. They are related as follows:
• Cone A has radius of r and height of h.
• Cone B has 3 times the height of Cone A but has the same radius.
• Cone C has 4 times the radius of Cone A but has the same height.

A. Determine the ratio, A:B:C, of the volumes of the cones?

B. What Knowledge do you apply for this question and what did you learn from this lesson?

Respuesta :

Answer:

True.

Here, radius of the sphere = radius of the cylinder = r

Diameter of the sphere = height of the cylinder = 2r

Surface area of the sphere = 4πr2

Curved surface area of the cylinder = 2πr (2r) = 4πr2
