Area = (radius)2 x pi
Area = 82 x pi
Area = 64 x pi
Area ≈ 201.06 square inches
If the circle has a diameter of 8 inches, it's 50.265 square inches. If the circle has a radius of 8 inches, it's 201.06193 square inches. In the odd case that the circle has a circumference of 8 inches, it's 5.09296 square inches.
Area of a circle: pi*radius squared
The radius of the circle is 21 inches. The area of the circle is (pi) times (radius squared) = pi times 441 = 1,385.44+ square inches. 1 square foot = 144 square inches. The area of the circle is (1385.44+ square inches) divided by 144 = 9.621 square feet (rounded to 3 decimal places).
Radius of circle: square root of (113.04/pi) = 5.9985 inches rounded to 4 decimal places
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.
Area of the circle in square inches = pi*82
The radius of a circle with an area of 35 square inches is 3.34 inches.
The radius of a circle with an area of 706.50 square inches is: 15 inches.
A circle with a radius of 26 inches has an area of: 2,124 square inches.
pi*radius2 = 100 square inches Making the radius the subject of the above equation gives it a value of 5.641895835 inches.
