Question

Curved surface area of the frustrum

Answer 1

Answer:

CSA of frustum is

π(R + r)l

where, R = radius of bigger surface

r= radius of the smaller one

l = height of the frustum

Answer 2

Curved surface area of frustum of cone is :

pi*l(R+r)...

here l=slant height of frustum

R = radius of bigger circle

r= radius of smaller circle
