6. The total surface area of a right cone is 1.760 cm' and the radius of its base is 14 cm. Find the following for the cone
​

Answer 1

Answer:

I am not sure but it will be helpful to you

Step-by-step explanation:

We know that the total surface area S of a right circular cylinder of radius r and slant height l is given by

S=πr

2

+πrl=πr(r+l)

Here, r=12mandl=9m

∴S={
