The lateral area is given by: [tex] Al = \pi * r * g
[/tex] Where, r: cone circular base radius g: inclined height Substituting values we have: [tex]Al = 3.14 * 3 * 8.5
Al = 80.07 cm ^ 2[/tex]
The surface area is given by: [tex] A = Al + \pi * r ^ 2
[/tex] Where, r: cone circular base radius Al: lateral area Substituting values: [tex]A = 80.07 + 3.14 * (3) ^ 2
A = 108.33 cm ^ 2[/tex]
