Hey!

Question #2:
The question gives us the diameter (6.4cm.) and the height (13cm.)
To find the radius, divide the diameter by 2: 6.4 / 2 = 3.2cm.
I can fill out the info box with:
- Height = 13cm.
- Radius = 3.2cm.
- Diameter = 6.4cm.
Now, I can fill in the blanks.
V = πr²h
V = π · 3.2² · 13
V = π · 10.24 · 13
V = π · 133.12
V ≈ 418.21 or V = 133.12π
The volume of the canister is 418.21 centimeters³

Question #3:
The question gives us the diameter (10cm.) and the height (6cm.)
To find the radius, divide the diameter by 2: 10 / 2 = 5cm.
I can fill out the info box with:
- Height = 6cm.
- Radius = 5cm.
- Diameter = 10cm.
Now, I can solve for the volume.
V = πr²h
V = π · 5² · 6
V = π · 25 · 6
V = π · 150
V = 471.24
Round.
471.24 → 471.2
The volume of the birthday cake is 471.2 centimeters³
