Question

curved surface area of a right circular cone of height 16 cm and base radius 12 cm is

Answer 1

Answer:

Step-by-step explanation:

Answer 2

399 cm^2.

1. Curved Surface Area of right circular cone is given by formula: pi*r*l, where pi can be considered as 3.14 or 22/7, r is radius of cone and l is the length of cone.
2. r=12 cm, h=16 cm.
3. l=root(r^2 - h^2)
4. l=root(256-144)
5. l=10.58
6. pi*r*l => 3.14*12*10.58 => 398.65 => 399
