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 of circle is pi*radius*radius. hence area of 1.5 inch circle is 7.065 square inches.
Area of a circle = pi*radius squared
Area of a circle: pi times radius squared
Area of a circle = pi times radius squared
Area of a circle = pi times radius squared
A four-inch radius circle has an area of about 50.27 square inches.
The approximate area of a circle with a 12-inch diameter is: 113 square inches.
Area of circle is pi*radius*radius. hence area of 1.5 inch circle is 7.065 square inches.
The area of Circle S can be found by using the area formula for circles. The area of a circle is pi times the radius squared. So, the area of Circle S with a 1 inch radius is Pi inches squared.
Area of a circle = pi*radius squared
Area of a circle: pi times radius squared
Area of a circle: pi times radius squared
The area is 254.47 in2
Area of a circle = pi times radius squared
Area of a circle = pi times radius squared
Area of circle = pi*r2 where r is the radius. So here, area = 63.617 sq inches
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.
