What is the area of 9 inch diameter circle?
Area= pi × radius2 Area= 3.14 × (4.5 in2) Area= 3.14 × 20.25 Area= 63.585 in2 The answer is 63.585. You would find this answer by doing this: 20.25 x3.14 _______ 8100 20250 +607500 _______ 635850 Then you would take the zero off the end.
If a circle as the radius of 9 cm what is its area?

What is the area of a 12 inch and a 9 inch circle?
If you are talking about 9 and 12 inch diameter, then divide both by 2 to get the radius. The area of a circle is pi (3.1415 is good for most calculations) multiplied by the square of the radius. So for the 12 inch circle, the radius is 6. The square of the radius is 36, and multiplying this by pi gives approximately 113.1 square inches. Now the 9 inch circle has a radius of 9/2 or 4.5. Squaring this we get 20.25, which multiplied by pi is approximately 63.6 square inches. If 9 and 12 were already the radius in the problem, just don't divide by 2 since you already have the radius.
If the radius of a circle is two inches what is the area and circumference?
2 inch radius = 12 9/16" circumference & an area of 12.56637 sq. inches.
How many times greater is the area of a 6 inch circle to that of a 2 inch circle?
Radius is 3 times as large so area is 3*3 = 9 times as large.

A circle with a radius of 9 feet has an area of 254.47 square feet.
If The exact area of a circle is 81pi square inches what are the radius and diameter of the circle explain?
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches
Is the area of two 3 inch circles equal to the area of a 6 inch circle?
No. Area of 3 inch circle is 9/4 pi so two of them total 9/2 ie 4.5 pi. Area of 6 inch circle is 9 pi, the equivalent of 4 of the smaller circles!
