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)
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 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
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.
