A cylindrical jar of peanut butter measures 7 cm in diameter and 12 cm in height. If 1 cm³ = 0.034 ounce,
about how many ounces of peanut butter can the jar hold?
64 ounces
8 ounces
16 ounces
32 ounces

Respuesta :

  • Radius=r=7/2=3.5cm
  • h=12cm

Volume

  • πr²h
  • π(3.5)²(12)
  • 12π(12.25)
  • 461.58cm³

Convert to ounces

  • 461.58×0.034
  • 15.7oz
  • 16oz

Option C

Answer:

16 ounces (nearest ounce)

Step-by-step explanation:

Formula

Volume of a cylinder = πr²h  (where r is the radius and h is the height)

Diameter = 2r  (where r is the radius)

Given:

  • diameter = 7 cm
  • height = 12 cm

⇒ radius = 7 ÷ 2 = 3.5 cm

⇒ Volume of the jar = π · 3.5² · 12 = 147π cm³

If 1 cm³ = 0.034 ounce, then

⇒ Ounces jar can hold = 147π × 0.034

                                      = 15.70168008

                                      = 16 ounces (nearest ounce)
