Question

Find the volume of a cylinder when the radius is 9 cm and the length is 20 cm

Answer 1

Calculate the area of the circle= pir^2
= 254,5 cm x height (20)
=45804,42 cm^3

Answer 2

Answer:

5089.38 cm OR 1620π

Step-by-step explanation:

The formula for the volume of a cylinder is π$r^{2}$h so if the radius is 9, 9 squared is 81. We multiply 81 by 20 and that gives us 1620. So in terms of pi, it is 1620π but if you just multiply it all together, it gives you 5089.38 cm. Please mark me brainliest and I hope this helped!
