? A mug can hold 13.46 oz of coffee without overflowing. The radius of the mug is 3 cm. Given that 1 cm3 equals 0.034 oz, what is the height of the mug to the nearest centimeter?

Respuesta :

Answer:

14 cm

Step-by-step explanation:

Given:

A mug can hold 13.46 oz of coffee.

The radius of the mug is 3 cm.

Given that 1 [tex]cm^{3}[/tex] equals 0.034 oz.

Question asked:

What is the height of the mug to the nearest centimeter ?

Solution:

Given that 1 [tex]cm^{3}[/tex] equals 0.034 oz.

By unitary method:

0.034 oz = 1 [tex]cm^{3}[/tex]

1 oz = [tex]\frac{1}{0.034}[/tex]

13.46 oz = [tex]\frac{1}{0.034}\times13.46 =395.88 \ cm^{3}[/tex]

A mug can hold 13.46 oz of coffee means volume of cylinder is given which is 395.88 [tex]cm^{3}[/tex]. Now we can find the height of the mug by using volume of cylinder formula:

volume of cylinder = [tex]\pi r^{2} h[/tex]

                   [tex]395.88=\frac{22}{7} \times3\times3\times \ h\\395.88=\frac{198 \ h}{7}[/tex]

By cross multiplication:

                 [tex]395.88\times 7 =198\ h\\2771.16= 198\ h[/tex]

By dividing both side by 198

[tex]h = 13.99[/tex] [tex]cm[/tex]

Therefore,  height of the mug to the nearest centimeter is 14 cm.
