Madelyn makes a strawberry smoothie in the blender before swim practice. The smoothie occupies just a little more than 38 cubic inches of space in the blender pitcher. When it is time to pour the smoothie into a cylindrical plastic cup, she has three sizes to choose from. Determine whether or not the each of the three cups is large enough to contain all of the strawberry smoothie. Use 3.14 for pi

Cup A with a height of 7 inches and a diameter of 3 inches is ___ to contain the entire strawberry smoothie.
A. large enough
B. too small

Cup B with a height of 5 inches and a radius of 1 inches is ___ to contain the entire strawberry smoothie.
A. large enough
B. too small

Cup C with a height of 6 inches and a diameter of 2.5 inches is ___ to contain the entire strawberry smoothie.
A. too small
B. large enough

Consider the cup a cylinder. The formula for the volume of a cylinder is: V= PI x r^2 x h

Cup A: 3.14 x 7 x 1.5^2 = 49.46

This is large enough

Cup B: 3.14 x 5 x 1^2 = 15.7

This is too small

Cup C: 3.14 x 6 x 1.25^2 = 29.44

This is too small.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
