Circumference = 2 x pi x radius. If you want an estimate, you can round some of the numbers involved - either the radius, or pi, or both.
Radius = circumference/2pi, in this case 69/2pi or 34.5/3.14, as near 11 cm as makes no difference.
To find the area of a circle with a given circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Plugging in the values, we get A = (42^2) / (4π) = 1764 / (4π) ≈ 140.72 square units.
circumference = 2*pi*11 = 69.115 inches to 3 dp
C = ~34.56 inches.
eleven (11) inches
The circumference of a circle with a radius of 11 is: 69.12
The radius is 11.
A circle with a radius of 11 units has a circumference of 69.12 units.
The circumference of a circle with a radius of 11 is about 69.12The general formula is circumference = (2 x radius) x pi. Therefore, in this instance, the answer is 2 x 11 x pi = about 69.12.
The circumference of a circle with a radius of 11 is about 69.12 centimeters.The general formula is circumference = (2 x radius) x pi. Therefore, in this instance, the answer is 2 x 11 x pi = about 69.12
It is: 2*pi*11 yards
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with an 11 cm radius, the circumference is ( C = 2\pi(11) ), which equals approximately 69.44 cm when using ( \pi \approx 3.14 ).
C = 69.115 inches.
The circumference of a circle is the same as the perimeter of a circle, so the perimeter and circumference would both be 3 ft.
The formula for circumference is Radius X 2 X pi so for a radius of 11 meters is 11X2X3.1416= 69.12 (but because the accuracy of the radius measurement of 2 decimal places the answer is 69)
The answer depends on what the 11 m refers to radius, diameter or something else.
Radius = circumference/2pi, in this case 69/2pi or 34.5/3.14, as near 11 cm as makes no difference.
