Area = pi*62 = 113.0973355 or about 113.10 square inches
Remember that the area of a circle is (pi)r2, where r is the radius of the circle. You would plug the radius into the formula:
(pi)r2
(pi)(6)2
36 pi in2
Or, if you want to put it into decimal form, 113.097 in2
The area of a circle is given by (area) = (pi)*(radius)^2. So in this case, it would be:
(pi)*(6 inches)^2 = 36(pi) square inches
Area of a circle: pi*radius*radius
12 inches because the radius is half of the diameter, and 6 x 2 is 12.
The formula for area of a circle is: A = (pi)*r^2 If the diameter of a circle is 6 then the circle's radius is 3. So, A = (pi)*(3)^2 A= 9*(pi) inches squared or A = 28.26 inches squared (rounded)
A square doesn't have a radius. A circle has. If the area of a square is 72 inches2, then each of its sides is 6 sqrt(2) = 8.485 inches. (rounded)
A circle with a radius of 6 units has an area of 113.1 square units.
Area of a circle: pi*radius*radius

A circle with a diameter of 12 inches has an area of 113.1 square inches.A circle has an area equal to its radius squared times pi. Your circle has a radius of 6 inches (half the diameter)6 X 6 X 3.14159...=113.097336
What does the 12 inches represent? The RADIUS or the DIAMETER? It is NOT the area because 'square(sq)' is not in the question.
Area of a circle = pi*radius squared
The circumference of a circle whose radius is 6 inches is: 37.7 inches.
area = π × tradius² → area = π × 6² = 36π.
If the square touches the circle from the outside then its area is 6*6 = 36 square inches
The area ( A ) of a circle can be calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For a circle with a 6-inch radius, the area is ( A = \pi (6)^2 = 36\pi ). Approximating ( \pi ) as 3.14, the area is approximately ( 36 \times 3.14 ), which equals around 113.04 square inches. Thus, the approximate area of the circle is about 113 square inches.
Area = 38.485 square inchesCircumference = 37.7" (37.699")
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.
