Answer 1

hello....
Volume of cuboid=volume of cylinder
use this formula nd calculate the height .....
I hope you understand it.....
please mark it as a brainieist answer.......

Answer 2

volume of cuboid = l×b×h
volume of cylinder= πr²h
volume of cuboid = volume of cylinder
22×15×7.5=22/7 ×r² ×14
1275 =²²/7×r² × 14
by solving this you get
r²=56.25
r=7.5

I hope you will satisfy With my answer
