R=12.13
A=pi×r²
A=pi×12.13²
A≈462.2442041
A≈462.2 (to the nearest tenth).
So the answer is A≈462.2.

Answer:
Combined volume of the two game systems  
 cubic inches
Step-by-step explanation:
Volume of a cuboid = length × breadth × height
Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.
So,
Volume of Soham's video game system = 8 × 6 × 2 = 
 cubic inches
As Sean's video game system measures 1 inch longer on all sides,
the video game system measures 
 inches long, 
 inches wide, and 
 inches tall.
Volume of the video game system = 10 × 8 × 4 = 
 cubic inches.
Therefore,
Combined volume of the two game systems = 
 cubic inches
