Question

write the formula to find total surface area of cone and explain each term in it​

Answer 1

Step-by-step explanation:

. The formula for the total surface area of a right cone is T. S. A=πrl+πr2 . here, r is the radius and l is the slant height

Answer 2

Answer:

Total Surface Area (TSA) = Curved surface area + Area of Circular Base

Step-by-step explanation:

• A surface are of the cone is defined as when the area which is completed is covered by two surfaces. They are circular base and lateral curved surface area.
• The circular based area is calculated by using the formula of a circle. The lateral surface areas is calculated using area side of the cone.
• The surface are of the cone is a three-dimensional space of the region.

The formula to find the total surface is of the cone. It is as follows:

We know that,

Total Surface Area (TSA) = Curved surface area + Area of Circular Base

Total Surface Area of cone = πr2 + πrl = πr(l+r) square units.

Here, π is pie

R is radius

L in length
