Answer:
Volume of cylinder = πr²h
Volume of cylinder = 22/7 × 20×20 × 21
Volume of cylinder = 26,400 m³
THANK YOU!
DO THANK MY ANSWERS
the formula for finding the volume of of a hollow cylinder is = pi×(R‐r)×h
Step-by-step explanation:
now put the value
22/7×(20‐15)×21 = 22/7×5×21 = 22×5×3 = 330
Hence the answer is 330
HOPE IT HELP’S YOU
