Question

the ratio of total surface area is​

Answer 1

Answer:

Therefore, we will have the formula of the curved surface as 2πrh. Also, we have the area of the circle given by πr2. Since, there are two circles thus we get the total surface area of the cylinder given by 2πrh+2πr2 or Total surface area = 2πr(h+r). Hence, the required ratio of the respective areas is 4:3.

Answer 2

Answer:

GOOD EVENING MATE

Step-by-step explanation:

The general formula for the total surface area of a right prism is T. S. A. =ph+2B ,

where p represents the perimeter of the base, h the height of the prism and B the area of the base.
