Question

Given a cylinder with
r=8cm

h=2cm
Find the approximate value of the cylinder rounded to the nearest 10th

Answer 1

The formula for the volume of a cylinder is

V=πr²*h    where r=radius and h=height
plug in the data we know
V=π8²*2
V=π*64*2
V=128π
V=402.1cm³

Answer=402.1cm³

Answer 2

402.1cm³ is correct!
Thanks for asking 
Have a nice day!
