Vsphere=(4/3)pir^3
when we replace r with 2r
newvsphere=(4/3)pi(2r)^3
newvsphere=(4/3)pi8r^3
newvsphere=8((4/3)pir^3)
newvsphere=8(vsphere)
it's volume is multipliied by 8
that is choice C, because 2^3=8, it's vollume is 8 times original voluem
answer is C
Factors of 24 that would also add up to -10 would be -12 and 2 soo. you would factor out the n's to get:
(n-12)(n+2)
The answer would be 32" of paper. This is because I presumed the front is the length and hight so it the same for the back.
