Area = 22/7*72 = 154 square inches
Using 3.14 as Pi the area of circle is: 12.56
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
Area = (3.14) x (radius) x (radius) "Radius" means the distance from the center of the circle out to the circle's curved line.
A circle with a radius of 16 cm has an area of 804.25 square cm.
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with a 12-inch radius, the circumference would be ( C = 2\pi \times 12 ), which equals ( 24\pi ) inches. Approximating ( \pi ) as 3.14, the circumference is approximately 75.4 inches.
The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.

Draw two diameters perpendicular to each other. Draw a smaller circle with the same centre such that the radius of the inner circle is 'r' and the radius of the outer circle is 'r√2.' [Or, the radius of the outer circle is R and the radius of the inner circle is R/√2.]
area of a circle is equal to pi times the square of its radius.. A=(pi)r^2
Area = (3.14) x (radius) x (radius) "Radius" means the distance from the center of the circle out to the circle's curved line.
The area of a circle can be calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Given a radius of 100, the area of the circle would be A = π(100)^2 = 10000π square units. This simplifies to approximately 31415.9 square units.
The circumference of a circle is calculated using the formula C = 2πr, where C is the circumference, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Given a radius of 20, the circumference would be C = 2 * 3.14159 * 20 = 125.6636 units.
Circumference of a circle = 2*pi*radius
Using 3.14 as Pi the area of circle is: 907.46
The area of a circle is calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Plugging in the radius of 21cm into the formula, we get A = 3.14159 x (21)^2 = 1385.44 square centimeters. Therefore, the area of a circle with a radius of 21cm is 1385.44 square centimeters.
A circle with a radius of 16 cm has an area of 804.25 square cm.
