Question

This soda can is going to be made from aluminum. How many square centimeters of aluminum are needed if the

Answer 1

170.35 cm² are needed to make the can of soda (not in the choices)

Step-by-step explanation:

The surface area of a cylinder = 2πrh + πr², where

• r is the radius of its base
• h its height
• π is about 3.14

∵ The soda can is made from aluminum

∵ The can is shaped a cylinder with radius 3.5 cm

∴ r = 3.5

∵ Its height is 6 cm

∴ h = 6 cm

- The aluminium that needed to make the can is the surface area

   of the can

∵ The surface area of the can = 2πrh + πr²

- Substitute r by 3.5, h by 6 and π by 3.14

∴ The surface area of the can = 2(3.14)(3.5)(6) + (3.14)(3.5)²

∴ The surface area of the can = 131.88 + 38.465

∴ The surface area of the can = 170.345 cm²

- Round it to the hundredths' place

∴ The aluminium are needed = 170.35 cm²

170.35 cm² are needed to make the can of soda
