Which measuring device is used to take the circumference of the body.?
A tape measure.
What is the radius of a circle if the circumference is 72?
The equation used to calculate circumference is C = Pi * R^2, where R is the radius and C is the circumference. If one knows the circumference and seeks the radius, then they must divide by pi. Next, they must take the square root. When the circumference is 72, the radius must be approximately 4.8.
How do you find area of a circle when you have the circumference circle?
Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)
What is the diameter of 27cm for area of circumference?
Oh honey, let me break it down for you. The diameter of a circle with a circumference of 27cm is about 8.59cm. You just take the circumference and divide it by π (that's pi for you math newbies). So there you have it, simple as pie... or should I say, simple as pi!
What is the circumference of the circular table whose radius is 56.12?
Multiply by 2xpi (that is, by about 44/7) to get 352.75 To find the circumference of an object, you take it's diameter and multiply it by pi. If we take an approximate pi (3.14), and multiply it by the diameter (which is 56.12 multiplied by 2, or 112.24), we get the formula: C=pi(d) C=3.14(112.24) C=352.4336 Therefore, the circumference of the table is about 352.4336 units
