Question

Write the formula of cone whose tsa of cone explain terms in it

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Therefore the total surface area of a cone $=\pi r (l+r)$

r = radius

l=slant height

Step-by-step explanation:

Cone: A cone is three dimensional shape.

The base of cone usually is a circle.

It has one face.

The volume of a cone $=\frac{1}{3}\pi r^2h$

r = radius of base.

h= height of the cone.

Slant height:The slant height of an object is a height which measures along the lateral face from the base to the apex of that object.

The slant height of an object is denoted by l.

The lateral surface area of a cone is $=\pi r l$

The area of the base which is a circle in shape is = $\pi r^2$

Therefore the total surface area of a cone $=\pi r l$+$\pi r^2$

                                                                                    $=\pi r (l+r)$

r = radius

l=slant height
