Question

Find the lateral area & surface are

Answer 1

The lateral area is given by:

`Al = \pi * r * g`
Where,
r: cone circular base radius
g: inclined height
Substituting values we have:

`Al = 3.14 * 3 * 8.5 Al = 80.07 cm ^ 2`

The surface area is given by:

`A = Al + \pi * r ^ 2`
Where,
r: cone circular base radius
Al: lateral area
Substituting values:

`A = 80.07 + 3.14 * (3) ^ 2 A = 108.33 cm ^ 2`
