the surface area of the sphere?
2 answers:
Answer:
it quadrupled
Step-by-step explanation:
FORMULA FOR SURFACE AREA OF SPHERE = 4 pi r^2
<span>r = 6 " area = 4 pi X 6 X 6 = 144 pi " squared </span>
<span>r = 12 " </span>
<span>area = 4 X pi X 12 X 12 = 576 pi" squared </span>
<span>ANSWER Area will be 4 times the original</span>
