Surface area SA:

Circumference C:

dividing this you get

and

Now let's input the radius

into the Surface area formula...
Ok I’ll follow you but I’m not active on it
The surface area of the cone is 
Explanation:
The diameter of the cone is 10 cms
Thus, the radius of the cone is given by

The slant height of the cone is 12 cms
The formula for surface area of the cone is given by

Substituting the values, we get,




Thus, The surface area of the cone is 
Answer:
(4/7) ÷ (7/5) = 20/49
Step-by-step explanation:
You show a sum, not a quotient.
Perhaps you want the quotient ...
(4/7) ÷ (7/5) = (4/7)×(5/7) = (4·5)/(7·7) = 20/49
