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 circle with the radius of 9 millimeters?
Using 3.14 as Pi the area of circle is: 254.34
What is the area of a 12 inch and a 9 inch circle?
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.
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.
What is the area of a circle with a radius of 9 ft?
A circle with a radius of 9 feet has an area of 254.47 square feet.
What happen to the area of circle when the radius is tripled?
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
What is the area of a circle with a radius of 9 centimeters?
The area of a circle with a radius of nine centimeters is: 254.5 cm2
What Is the area of a circle with a 6 inch diameter?
A=pi X radius squared 3.14 X 9=28.26 sq. inches
What is the area of a circle if the radius is 9 In?
Area of a circle of radius r = πr2Area of circle of radius 9 In = π(9)2 = π x 81 , putting value of pi we get= 3.14159625 x 81 = 254.46 sq. In

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!
