Using 3.14 as Pi the area of circle is: 1384.74

Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared

A circle with a radius of 75 feet has an area of 17671.458676442588 square feet. You calculate this by using the area of a circle formula, which is A=pi*r^2.

A circle with a radius of 12.5 feet (25/2) has an area of 490.87 square feet.

A=pi*radius^2 so 12/2=6 ==> radius so 36pi square feet is the area

A circle with a radius of 12.5 feet (25/2) has an area of 490.87 square feet.

Area of circle = PI * radius^2, so PI * 6^2 = 113.09733553 square feet.

The area of a circle is equal to pi*r2, where pi is the radius. In this case, the area is equal to pi*(7 feet)2, which is about 154 square feet.

The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.

Measure its radius in feet or derive it from the diameter or circumference. A circle with radius r feet has an area of pi*r^2 square feet.

A=pi*radius^2 so 12/2=6 ==> radius so 36pi square feet is the area

The area of a circle is calculate as:A = pi x r squared If the radius "r" is in feet, the area will be in square feet.

Radius of a circle with 20' circumference = 20'/2pi = 3.18'Area of a circle with 3.18' radius = ((3.18')^2)pi = 31.8 square feet

Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2
