Question 618616
One circular table has a diameter of 9ft, and another circular table has a diameter of 14ft. How much greater is the area of the larger table? round to the nearest whole number.
**
Area of a circle=&#960;r^2 or &#960;d^2/4
r=radius
d=diameter
That is, area of a circle is proportional to the square of the radius or diameter.
For given problem:
The 14 ft diameter table will have an area (14/9)^2&#8776;2.4 times greater than the area of the 9 ft table
