Answer 2

here we have to compute the volume V of our bucket. Now a volume V of a cylinder is giben by the subsequent formula:
\[V = \pi \times {r^2} \times h\]
where r is the radius of our buck, and h is the heoght of our buck.
so what is the volume V?

Answer 3

The volume would be 2416.23 @Michele_Laino

Answer 4

correct? @Michele_Laino

Answer 5

ok! that's correct.
Now we have to multiply that volume by 0.09, namely:
2416.23*0.09=...?

Answer 6

217.46
