$✤$CONE

A cone is a figure that has two surfaces.

• Flat Surface

• Curved Surface

The point on the top of cone is called APEX

The flat surface is Called BASE

$✤$RIGHT CIRCULAR SOLID CONE

A circular cone is a cone with circular right section

A right circular cone is circular cone whose axis is perpendicular to base

$✤$FORMULA TO DETERMINE THE SURFACE AREA

If Radius = r unit & Slant Height = l unit

Then Total Surface Area = $\pi \: r(r + l) \: \: sq \: unit$

$✤$CALCULATION

Here Radius = r =10 cm & Slant Height = l =25 cm

Then Total Surface Area =

= $\pi \: r(r + l) \: \: sq \: </em></strong><strong><em>cm</em></strong><strong><em>$

$= \pi \: \times 10 \times (10 + 25) \: \: {cm}^{2}$

$= \frac{22}{7} \times 10 \times 35 \: \: {cm}^{2}$

$= 1100 \: \: {cm}^{2}$
