What is the circumference for 12 cm?
Hence, The circumference of the circle is 75.4 cm.
What is the area of a 12cm circle?
The area of a circle is equal to Pi π times the radius r squared. Substitute in the value of the radius r=12 into the formula for the area of a circle. Pi π is approximately equal to 3.14 .
What is the diameter of radius 12 cm?
Now we are given a circle with the radius of 12cm. Hence the diameter of the circle is 2 × 12 = 24cm.
What is the circumference of a 12 inch circle in inches?
The circumference of a 12 inch circle is 37.70 inches.
What is the radius of 12?
≈38 and A. ≈113 . First you need to find the radius, the key term to find the radius is diameter=2⋅radius ; therefore the radius r is 122=6 inches.
How many diameters equal a circumference?
Ancient mathematicians figured out that the circumference of a circle is always a little more than three times the diameter of a circle. Since then, they narrowed that “little more than three times” to a value called pi (pronounced “pie”), designated by the Greek letter π.
What is the area of a circle of 10 cm?
Answer: The area of the circle with a diameter of 10 cm is 78.5 cm2.
What is the diameter of 12 m?

How to calculate the diameter of a circumference?
Formula: C = d x π Where, C = Circumference d = Diameter.
How to find the radius of a 10 cm circle?
To find the radius of a circle with a circumference of 10 centimeters, you have to do the following: 1 Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter, 3.18 centimeters. 2 Divide the diameter by 2. 3 And there you go, the radius of a circle with a circumference of 10 centimeters is 1.59 centimeters.
