Question

What's the lateral area of a right circular cone if the diameter of the base is 4 m and the slant height of the cone is 15m? Round your answer to the nearest whole number

Answer 1

r = 2m, l = 15m, d = 4m

Lateral Surface Area of a cone = πrl

= 3.14 x 2 x 15

= 6.28 x 15

= 94.2

= 94 sq. m (After rounding to the nearest)

Hope this helps you!
