Question

What is the radius of a cylinder if it has a volume of 769.3 cubic meters and a height of 5 meters? (Use 3.14 for π.)


7 m or 21 m

Answer 1

volume of cylinder is \[h \pi r ^{2}\]
V=769.3 and h =5 \[769.3 = 5(3.14)r ^{2}\]
\[r=\sqrt{\frac{ 769.3 }{ 5(3.14) }}\]

Answer 2

so 7 meter?

Answer 3

yes it's 7
