What is the circumference of a circle 1 meter round?
Circumference of a circle = 2*pi*radius or diameter*pi
What is the equation for the diamiter of a circle?
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
What is the radius of a circle with a circumference of 6.28 mm?
Radius of the circle: 6.28/2*pi = 0.999 mm or about 1 mm
What is the circumference of 8 inch circle?
The circumference of an 8-inch circle is: 25.1 inches.
How do you get the circumference of a circle with the area of 196 pi?
A= pi(r)^2C=pi*dr= 1/2(d)Area=196piSince you know that 196 has to be squared because of the Area formula, to find the radius, you take the square root of the number, this number is the radius of the circle. You also know that the circumference is pi times the diameter and you know the radius is half the diameter, or the diameter is twice the radius.sqrt(196)=1414=rd=28Circumference= 28pi
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
What is the circumference of a circle to give 1 meter square?
area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077
How do you find the circumference if you have the area of a circle?
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
What is the area and circumference of a circle with a radius of 1. also use 3.14159 for pie?
If the radius of the circle is 1, the area is pi. (3.14159 square units) The circumference is twice that. (6.28318 units)
The circumference of a circle is 62.8 feet What is the radius of the circle in feet and find the area of the circle?
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
What is the radius of a circle that has a circumference with the same numerical value as its area?
1
What is the circumference of a circle with a radius 1?

Area circle P 1 radius radius circumference equals 2 P1radius?
The area is pi x radius x radius The circumference is 2 x pi x radius pi = 3.14
What is the area of the circumference of a circle with diameter 7 yd?
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
Find the ratio of the circumference of 4Cm?
