Use the formula A=pi x r2. Divide the diameter by 2 then that gives the radius. Substitute the value for radius in the formula. Then that's the answer. (Use 3.14 for pi)
The area of a circle with a diameter of twelve inches rounded to the nearest whole number is 113 square inches.
Area = pi*6*6 square inches
The diameter of a circle with an area of 37.68 is 6.92
The diameter of a circle with a 12-foot circumference is about 3.82 feet. (circumference divided by Pi = diameter).
The area of a circle with the diameter of 3m is 7.069 m2
The area of a circle with diameter of 4.9 is 75.43 units2
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
The area of a circle with a diameter of 9.4 m is: 69.4 m2
Twelve inches is a length. It can be a diameter, but if it is a diameter, you would simply say 'The circle is 12 inches diameter'. So; how big is it - it is 12 inches.
A circle with a diameter has an area of 50.265486543928724876568901 sq. ft.
The diameter of a circle whose area is 200.96 is: 16
If the area of a circle is 8pi, its diameter is: 5.657 units.
