Doesn't know the answer. Sorry
1,185

Step-by-step explanation:

Can't do the solution but you can do it.

Just learn how to solve the multiplication with partitioning strategy, grid method, and expanded method. You can search it and learn it by watching and understanding how to solve all of them. But I want to say sorry, because I can't answer the number 4 cause I don't know to do it. Really sorry.

Hope it helps

Elan Coil [88]

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 $cm^{3}$ equals 0.034 oz.

Question asked:

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

Solution:

Given that 1 $cm^{3}$ equals 0.034 oz.

By unitary method:

0.034 oz = 1 $cm^{3}$

1 oz = $\frac{1}{0.034}$

13.46 oz = $\frac{1}{0.034}\times13.46 =395.88 \ cm^{3}$

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

volume of cylinder = $\pi r^{2} h$
