height of cone =3cm=perpendicular
p/b=tan60
3/b=root3
3/root3=b
(3×root3)/root3×root3 =b
3root3/3=b
root3=b=radius
volume of cone=1/3×pai ×r^2×h
=1/3×3.14×root3×root3×3
=(3.14×3)cm^3
=9.42cm^3
p/b=tan60
3/b=root3
3/root3=b
(3×root3)/root3×root3 =b
3root3/3=b
root3=b=radius
volume of cone=1/3×pai ×r^2×h
=1/3×3.14×root3×root3×3
=(3.14×3)cm^3
=9.42cm^3
