If a chessboard were to have pennies placed on each square such that 1 penny was placed on the first square, 2 on the second, 4 on the third, and so on (doubling the number of pennies on each subsequent square), how many pennies would be on the chessboard when finished?

The answer to your question is 414.48 ft²

Step-by-step explanation:

Data

height = 6 ft

diameter = 1 ft

# of fence posts = 12

amount of paint = ?

Formula

Area of a cylinder = πr² + 2πrh

Process

1.- Find the area of 1 cylinder

Area = (3.14 x 0.5) + (2 x 3.14 x 0.5 x 6)

Area = 15.7 + 18.84

Area = 34.54 ft²

2.- Calculate the area of 12 fencepost

Total area = 12 x 34.54

                = 414.48 ft²
