Given
Diameter of cone = 8 cm
Slant height of cone = 14 cm
Formula used:
Lateral surface Area of cone = πrl
Where, l = slant height
r = radius of cone
h = height
Solution:
Radius = Diameter/2 = 8/2 = 4 cm
Lateral surface area of the cone = πrl
= (22/7) × 4 × 14
= 176 cm²
Then the lateral surface are of the cone = 176 cm²
