A) 36 pi dam sqrd
B) 9 pi dam sqrd
C) 18 pi dam sqrd
D) None of the other choices

Answer 1

Consider a sphere of diameter 61 units. If the diameter is divided by 6 , how is the surface area of the resulting sphere affected?

Answer 2

If a sphere has radius r, the the surface area is
\[ 4 \pi r^2
\]

Answer 3

Replace \[ r= \frac {\text{dam}} 2\]

Answer 4

sa= 12 pi
