Let me carefully examine the image to identify which objects are cylinder-shaped.
First, I’ll recall the definition given:
*A cylinder is a solid object with two identical flat ends that are circular or elliptical and one curved side.*
Now I’ll go through each object:
1.
Candle – It has two flat circular ends (top and bottom) and a curved side. Even though the top has a wick and melted wax, the main body is cylindrical.
✔
2.
Soda can – Classic cylinder: two flat circular ends, curved side.
✔
3.
Top hat – The brim is flat but wide; the crown is tall and round, but the whole object isn’t a *single* cylinder—it has a flared brim and a different shape at the base. Not a pure cylinder.
✘
4.
Log (wood) – Cut log: two flat circular/elliptical ends, curved bark side. Yes—this is a natural cylinder.
✔
5.
Ice cream cone – Cone shape (pointy), not two flat ends. The ice cream on top is spherical.
✘
6.
Die (dice) – Cube: 6 flat square faces. Not a cylinder.
✘
7.
Gift box – Rectangular prism (box shape). Flat rectangular faces.
✘
8.
Drink cup with straw – Looks like a paper cup: slightly tapered (wider at top), so ends are not *identical* circles. Technically a *frustum*, not a true cylinder. In many elementary contexts, it might be accepted, but strictly speaking, a cylinder requires *identical* circular ends. Since the definition says “two identical flat ends”, this does
not qualify.
✘
So the true cylinders are:
- Candle
- Soda can
- Log
Let me double-check using the zoom tool on ambiguous ones.
Parent Tip: Review the logic above to help your child master the concept of cylinder worksheet.
