  (c) 16/9·π²·r⁶

Step-by-step explanation:

The water displaced is equivalent to the volume of the sphere, given as

  V = (4/3)π·r³

The product of two identical displaced volumes will be ...

  V² = ((4/3)π·r³)² = (4/3)²·π²·r⁶

  = 16/9·π²·r⁶ . . . . . . matches choice (c)

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
