Answer:
c. 3
Step-by-step explanation:
You just multiply the pre image points by 3 and you get the image.
Vsphere=(4/3)pir^3
Voriginal=(4/3)pir^3
when radius is multiplied by 4
replace r with 4r
Vnew=(4/3)pi(4r)^3
Vnew=(4/3)pi(64r^3)
Vnew=(64)(4/3)pir^3
Vnew=(64)(Voriginal)
the volume is 64 times the original
X is 9 Y is 3 and Z is 12
