Question

Kenny likes to count his money by tiling it on his table as shown. The diameter of a quarter is 24.26 mm. Find the area of the table not covered in quarters. Round your answer to the nearest hundredth.

Answer 1

The solution would be like this for this specific problem:

A (table) = 4(24.26) * 6(24.26)

= 14,125.1424

 

A (quarter) = pi*r2

= 469.9

 

Total area (quarters) = 462.24 * 24

= 11,093.76

 

Area (not taken) = A (table) – Total Area (quarters)

= 14,125.1424 - 11,093.76

= 3,031.3824

= 3,031.38

The area of the table not covered in quarters is 3,031.38 mm2.
