One circular table has a diameter of 8 ft, and another circular table has a diameter of 12 ft. How much greater is the area of the larger table?

20π sq ft ≈ 62.83 sq ft

Step-by-step explanation:

Area of table with diameter 8 ft = π*8^2/4 = 16π

Area of table with diameter 12 ft = π*12^2/4 = 36π

Difference between the area of the tables ;

= 36π - 16π

= 20π sq ft ≈ 62.83 sq ft                              ( π = 3.14)

62.83

Step-by-step explanation:

First, you have to find the area of both using the area formula for a circle:

A =

Radius is half of the diameter:

A = (3.1415926535...)( )         A = (3.14159265...)( )

A ≈ 50.265...                             A ≈ 113.097...

How much greater:

A - A ≈ 62.83185

i believe the correct answer is b.
