Question

One circular table has a diameter of 9 ft, and another circular table has a diameter of 14 ft. How much greater is the area of the larger table? Round to the nearest whole number.

Answer 1

Area Formula for a Circle is:
A = pi * r^2
pi * (4.5)^2 = pi*20.25
pi * 7^2 = pi*49 =
49pi-20.25pi = 90.32

The Larger table is 90.32 sq ft bigger than the smaller table.
