Answer from: owenr4758

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)

Answer from: 2019johnfranken

62.83 $ft^{2}$

Step-by-step explanation:

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

A = $\pi$ $r^{2}$

Radius is half of the diameter:

A $_{1}$ = (3.1415926535...)( $4^{2}$ ) A $_{2}$ = (3.14159265...)( $6^{2}$ )

A $_{1}$ ≈ 50.265... A $_{2}$ ≈ 113.097...

How much greater:

A $_{2}$ - A $_{1}$ ≈ 62.83185
