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

-------------------------------------------------

Hope This Helped! Good Luck!
