Question

any one know plz plz plz

Answer 1

as curved surface area of cone is equal to 2*pie*r*h....where pie is constant and equal to 22 divided by 7 and r&h are the radius & height of cone respectively

by putting these values in the formula we get
440 cm^2 =2*(22/7)*7*h
h=440/44
which is equal to 10
so height of cone is equal to 10 cm...
