2 inches. the radius is half of the diameter
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.
Diameter = 1/2 of the circle's radius. Diameter = 2 times the square root of (the circle's area/pi) Diameter = the circle's circumference/pi
Assuming that "1 inch round circle" refers to a circle whose circumference is 1 inch, its area is 51.34 sq mm.
If the radius is 1, the diameter is 2, and the circumference is about 6.28. Since the area of a circle is πr^2, a circle with r=1 would have an area of π.
Area = pi * diameter * diameter /4 = 3.14 * 1 *1 /4 = approx = 3/4 of square inch
Calculate the radius, which is simply 1/2 the diameter. Then use the standard formula for the area of a circle. ________________________________________________________________ The circle area = (pi) x diameter / 4 = 3.14 x 25/4 = 19.625 Sq inch
Area = (pi) x (1/2 of the diameter)2 11-inch diameter ==> 95.033 square inches of area (rounded)
1" if it's a 1" diameter circle, 2" if it's a 1" radius circle.
It is because your 1 inch is one circle 1 inch one circle one of each get it.
To me, "one-inch-circle" sounds like one inch IS the diameter.
2 inches. the radius is half of the diameter
The formula for finding the area of a circle is pi * r², where pi = 3.14; * = multiply; r = 1/2 of the diameter; and ² = squared (multiplied by itself). An example of how to calculate the area of a circle with a 6 inch diameter (3 inch radius): a = Pi * r² a = 3.14 * 3² a = 3.14 * 9 a = 28.26
Area of a circle = (1/2 x diameter)2 x piArea of a 24 inch diameter circle:(12 inches)2 x 3.1416 = 144 square inches x 3.1416 = 452.4 square inches
In a circle, Area = pi times radius squared: A = (pi)(r^2) Since the diameter equals 2 inches, the radius is one inch: A = (pi)(1^2) A = pi = 3.14 inches squared
Area of a circle = (1/4) x (pi) x (square of the diameter)
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.
