The Slant Height Of A Right Circular Cone Is 10 M And Its Height Is 8

1.	The Slant Height Of A Right Circular Cone Is 10 M And Its Height Is 8 M. Find The Area Of Its Curved Surface?
Answer» L = 10m h = 8m so R = √(l^2 - h^2) = √(10^2 - 8^2) = 6M So CURVED surface area = (π * r * l) = ( π * 6 * 10) M2 = 60π m2. l = 10m h = 8m so r = √(l^2 - h^2) = √(10^2 - 8^2) = 6m So Curved surface area = (π * r * l) = ( π * 6 * 10) m2 = 60π m2.

The Slant Height Of A Right Circular Cone Is 10 M And Its Height Is 8 M. Find The Area Of Its Curved Surface?

Answer»

L = 10m

h = 8m

so R = √(l^2 - h^2) = √(10^2 - 8^2) = 6M

So CURVED surface area = (π * r * l) = ( π * 6 * 10) M2 = 60π m2.

l = 10m

h = 8m

so r = √(l^2 - h^2) = √(10^2 - 8^2) = 6m

So Curved surface area = (π * r * l) = ( π * 6 * 10) m2 = 60π m2.
