Question

The diameter of the base of a cone is 12 meters and diagonal height is 10 meters.
Calculate the entire surface area of a cone.
​

Answer 1

the TSA of cone is 301.71

Answer 2

Answer: 2112/7 cubic.meter

Step-by-step explanation:

Given : diameter = 12m; slant height = 10m

To find: TSA of the cone

Solution:

TSA of the cone = πr (r + l)

= 22/7 x 6 ( 6 + 10)

= 22/7 x 6 x 16 = 2112/7 cubic metre
