Question
Calculate the volume of this composite figure. Use the pi button on your calculator and round the answer to the nearest tenth.
- 1205.5 ft3
- 4923.5 ft3
- 4825.5 ft3
- 1206.4 ft3
Hint:
We are given a composite figure. The given figure is made up of cone and cylinder. We will find their volume sperately and add them together to find the total volume.
The correct answer is: 1206.4 ft3
We will find the volume of cone and cylinder seperately and add them together.
Volume of cone is
Volume of cylinder is
= 804.25 cm3
Now, total volume will be the sum of the above volumes.
Total volume = 402.12 + 804.25
= 1206.4 cm3.
The volume of given figure is 1206.4 cm3.
For such questions, we should know the formula of volume of different shapes.
