Question

volume of cone is 6280 cm cube and its base radius is 20 cm find perpendicular height if Pi is equal to 3.14

Answer 1

bu..................m

Answer 2

we know ,
volume of cone =1/3pi.r.square h. (1/3pi,r^2.h)
according to given,
radius of cone=20cm
volume of cone=6280cm
so

let height be h
putting the values in formula

6280=1/3×3.14×400×h
6280=1256/3×h
6280=418.66667×h
6280/418.66667=h
14.99999...=h

so Answer is ........h(perpendicular height)= 15cm

hope this helps you:)
