Here,
Volume of cone =1/3pi*r^2*h
1/3*22/7*30*30*h=6280
6600/7*h=6280
h=(6280*7)/6600
h=749/165
h=4.53cm
Volume of cone =1/3pi*r^2*h

Volume of Cone = 1/3 πr²h
6280 = 1/3 × 22/7 × 30 × 30 × h
h = 6280 × 7/22 × 1/30 × 1/30 × 3
h = 2.22 × 3
h = 6.66 cm (approx)

And by the way according to me your answer is wrong
So delete it
In your answer you had forgot the ruled of multiplication
After the sign of =all the rules are changed
As multiply get convert into divide
