you have to quote the diameter or radius or circumference of the circle to calculate the area. If diameter 78.53. If radius 314.15. If circumference 7.95
Area = pi*52 = 78.53981634 square inches
A circle with a radius of 26 inches has an area of: 2,124 square inches.
pi*10*10 square inches
formula used is (pi)x(radius squared)= square inches (3.14)x(5x5)= 78.5 square inches
The area of the sector of a circle which has a diameter of 10 inches if the length of the arc is 10 inches is: 25 square inches.
The area is 78.5 square inches.
The largest square that could fit in a circle of diameter 10 inches has dimensions 5sqrt(2) inches by 5sqrt(2) inches.
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
Area of circle: pi*10^2 = 314.159 square inches rounded to 3 decimal places
Area of any circle = (pi) x (Radius)2Radius = 1/2 of diameterArea = (pi) x (10)2 = 100 pi = 314.16 square inches (rounded)
pi x 10² = 100 pi = 314.159265... square inches
The area of a circle = (pi)(radius squared); radius = 1/2 the diameter. Therefore, this circle has an area of (pi)(52) = 79 square inches, to the justified number of significant digits.
