How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
What is the area of a 3 inch diameter circle?
The area of the circle with a 3 inch diameter is pi*1.5^2 = 7.069 square inches roundedArea = Aradius of circle = rpi = 3.14159265A = pi x r^2A = 3.14159265 * (1.5) ^ 2A = 3.14159265 *2.25A = 7.06858The area of the circle is pi*1.5^2 = 7.069 square inches rounded
If a circle has a radius of 1 inch what is the circle's diameter?
2 inches. the radius is half of the diameter
What is the radius of a 38 inch circle?
It is customary to call a circle a 38 inch circle if its diameter is 38 inches. If that is the case, the radius = diameter/2 = 19 inches.
How many square inches are in a 10 inch diameter circle?
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.
What is the area of 2 inch diameter circle?
Area of a circle = pi times radius squared
What is the area of a 28 inch diameter circle?
The diameter of a 28-square inch circle is: 5.971 inches.
What is the area of a circle that has a 25 inch diameter?
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
What is the area of a circle that has a 1.5 inch diameter?
Using 3.14 as Pi the area of circle is: 1.7662499999999999
How many square inches are in a 11 inch diameter circle?
Area = (pi) x (1/2 of the diameter)2 11-inch diameter ==> 95.033 square inches of area (rounded)
What is the area of 20 inch diameter circle?
Area of circle: pi*10^2 = 100*pi square inches
Area of a circle with 2 inch diameter?
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
What is the difference in area that is 18 inches in diameter and 9.6 inches in diameter?
Area of circle with 18 inch diameter = pi*(18/2)2 = 81*pi sq inches Area of circle with 9.6 inch diameter = pi*(9.6/2)2 = 23.04*pi sq inches Difference = (81 - 23.04)*pi = 182.09 sq inches.
What is the square inch of a 2.5 inch circle?
Diameter = 2.5 inch so area = pi*(2.5/2)2 = 4.91 sq inches.
How many square inches in a 24 inch Diameter circle?
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
What is the radius of a 52 inch diameter circle?
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
What is the area of a circle with a 13 inch diameter?
Area = Pi(d/2)2 = Pi*6.52 = approximately 132.73 inches2
