, and its height is 39cm
. What is the volume of the bin? Use the value 3.14
for π
, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.

Answer 1

• 11052 cm²

Explanation:

Volume of cylinder:

• V = πr²h

Given:

• d = 19 cm ⇒ r = d/2 = 19/2 cm = 9.5 cm
• h = 39 cm
• π = 3.14

Find the volume:

• V = 3.14*9.5²*39 = 11052 (rounded)
