Question

a cone has base area is 154 meter square and its curved surface area is 550meter square find its volume

Answer 1

πr^2=154by solving
r=7..

πrl=550...putting.r in this..we get ..
l=25....
by pythgoreous theorem
h^2+r^2=l^2
h^2= 25^2-7^2
h=24
....
Volume= πr^2h/3
putting all values we get..
V=1232
