We have to find the scale factor.
A scale factor is a number which scales, or multiplies, some quantity. The ratio of any two corresponding lengths in two similar geometric figures is also called a scale factor.
Therefore, Scale factor =
= 1.25
And we can observe,,
Therefore, 5 is the scale factor.

Answer:
The cup can hold 235.5 cubic cm of popcorn.
Step-by-step explanation:
A cone shaped popcorn cup has a radius of 5 cm and a height of 9 cm.
Use 3.14 as an approximation for pi.
Now, to find cubic cm of popcorn the cup can hold.
Radius (r)= 5 cm
Height (h)= 9 cm
= 3.14 (as per question).
So, to get the cubic cm of popcorn the cup can hold we put formula of volume:
Volume= r
h
3
Volume= 3.14 x 5 × 9
3
Volume= 3x14 x 25 x 3
Volume= 235.5 cubic cm.
