OK, The circumference of a circle is 2 times pi (3.14) times the radius. SO the radius is = to circumference (5cm) divided by 2 times pi. 5 divided by 6.28 = .796 time 2 gives us a diameter of = 1.59 centimeters. We could also use Pi = cicumference/diameter therefore 3.14=5/x Multiply both side by x and 3.14 x = 5 Divide both sides by 3.14 and you get x= 5 divided by 3.14 which equals 1.59 cm
A radius is not a specific unit of measurement - the radius of a circle is the measurement from the centre of the circle to any line on the circle's circumference. The word "radius" is derived from the Latin word for "ray" but was also used to refer to the spoke of a chariot wheel.
A 7 centimeter circle has a diameter of 7 centimeters and a radius of 3.5 centimeters. The formula to calculate the area of a circle is πr^2, so for a circle with a radius of 3.5cm, the area would be approximately 38.48 square centimeters.
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
The circumference of a circle when the diameter is 30 is: 94.25
The formula for the circumference of a circle is C = 2πr, where r is the radius. Substituting 8.1 for the radius, we get C = 2 * π * 8.1 ≈ 50.92. Therefore, the circumference of the circle is approximately 50.92.
A circle with a radius of 15.5 centimeters has a circumference of 97.39 centimeters.
A circle with a radius of 2.8 centimeters has a circumference of 17.59 centimeters.
A circle with a radius of 4.5 centimetres has a circumference of 28.27 centimetres.
A circle has the radius of 27.7 cm what is the approximate circumference of the circle? The circumference is approx. 174 centimeters.
Circumference of a circle = 2*pi*radius or diameter*pi
The radius is 7cm
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
The radius is: 4.802 cm
11.00
A circle that is 25.13272 cm in circumference.
To find the radius of a circle when given the circumference, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 132 cm, you can plug this value into the formula: 132 = 2πr. To solve for the radius, divide both sides by 2π: r = 132 / (2π) ≈ 21 cm. Therefore, the radius of the circle is approximately 21 centimeters.
circumference = 2*pi*9
