The diameter of the circle will be: 26.1 inches.
Surface area = 4*pi*82 = 804.248 square feet rounded to 3 dp
Area of the circle = pi*7.82 = 191.134497 Approximate area = 3*82 = 192
It is: pi*82 = 64*pi square units
Area = pi*82 = 201.062 square m and rounded to 3 dp
Area = 5,281.02 inches2
Formula for finding the area of a circle: Area = pi * r2 a = 3.14 * 82 a = 3.14 * 64 a = 201.06
The area of a circle is worked out using the formula: area = Pi x (radius x radius) (a.k.a Pi r2 <- sorry, no Pi symbol available. ) The diameter is always twice the radius (the radius is the distance from the edge of the circle to the centre, the diameter is the distance from one edge to the other, through the centre). So, if your circle has a diameter of 16 feet, the radius will be 8 feet. Area = Pi x 82. = Pi x 64. Pi = 3.14159 So... Area = 3.14159 x 64 = 201.1 feet2.
Area = pi*82 = 201.062 square units to 3 d.p.
Area = pi*82 = 201.062 square inches rounded to 3 d.p.
A = pi * r2so:A = 3.14 * 82 = 200.96 square meters
area = pi*r2 2r = d r = 8 inches area = pi*82 area = 64pi
Area of the circle = pi*82 = 201.062 square inches rounded to 3 dp
Area in square units of measurement = pi*82 = 201.062 rounded to 3 decimal places
The diameter of the circle will be: 26.1 inches.
Area = pi*3/82 = 0.4417864669 or 0.442 correct to three decimal places
pi x r x r = 82 r x r = 82/3.1415 = 26.10 r = square root of 26.10 = 5.109 Hence diameter = 2 x 5.109 = 10.218 inches
