Answer:
440 times
Step-by-step explanation:
First you need to find the total number of cubes each student recieves (25)
Now you put it into a ratio 11 : 25
After that make another ratio with 1000 and solve for x
x : 1000
25x = 11000
x = 440
I think the correct answer is C. Since a=πr², in order to get the area to become 1/4 of what it was previously, the radius needs to be cut in half to make the divide that side by 4. a=π(r/2)²=πr²/4 and will therefore multiply the area by 1/4.
