Question

Which can cover a greater area? Use 3.14 .

2 nickels, each with a diameter of 0.8 inch.
1 dollar coin, with a diameter of 1 inch.
3 dimes, each with a diameter of 0.5 inch.
2 pennies, each with a diameter of 0.7 inch.

Answer 1

Answer: The two nickels.

Explanation:

Work out the area of all:

3.14 x 0.4 squared because to work out area its pi x r squared.

dollar = 0.5 squared times 3.14

dimes = 0.25 times 3.14 times by 3

pennies = 0.35 x 3.14 times 2

when worked out the two nickels are the highest amount of area covered.
