What is the derivation of the formulae of the surface area of a cone?

You can approximate the surface area by lots of triangles (base of the triangle on the base of the cone, and tip of the triangle at the tip of the cone), and analyze what happens when the triangles get narrower and narrower.


What does the s stand for in the formula for the surface area of a cone?

it stands for the total surface area

The surface area formula for a right cone is the same as the surface area formula for an oblique cone?

False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.


What is the surface area of a cone with a diameter of 15 and a slant height of 15?

A cone with a diameter of 15 and a slant height of 15 will have a total surface area of about 530.14 units2


What is the formula to find total area of a cone?

Curved Surface Area of a Cone:Multiply the base radius of the cone by pi. Multiply your answer by the length of the side of the cone.Then add the surface area of the base of the cone using the area of a circle = pi x r2


What will be the total surface area of a cone whose radius is 2r and slant height is half?

Total surface area = (piradius2)+(piradius*slant length)


What is the surface area of a cone with a slant height of 22 cm and radius of 7 cm?

A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2


How do you find the surface area of a cone?

A cone has two surfaces, lateral surface and its circular surface at the base.The surface area of a cone is the sum of the areas of these two surfaces, i.e. (1) area of the lateral surface and (2) area of its base.Let us consider a right circular cone to find its surface area.The lateral surface area of a right circular cone is π r lwhere,r is the radius of the circle at the bottom of the cone, andl is the lateral height of the coneThe surface area of the bottom circle of a cone is the same as for any circle, π r2Thus the total surface area of a right circular cone is: π r l + πr2 OR π r (l + r)


What is the surface area of a right cone with the radius of 4 and height of 13?
