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
