What is the Circumference if the diameter is 7.2?
Circumference of circle: 7.2*pi units or 7.2 * 3.14159265 = 22.6194671 with rounded values for pi and the resulting circumference.
How do you fimd the radius and diameter of a circle?
If you know the circumference, use the formula for circumference (C=pi*diameter), but rearrange it to get Diameter= circumference/pi. Then just sub in values.
What are the area, formulae, and plug-in values of a circle circumference of 12 ft?
?
What is the radius of a circle which has equal numeric values for the circumference and the area?
r = 2
What is the radius of a sunflower with a circumference of 46 cm?
The formula is: circumference = 2 x pi x radius. As always when you use a formula, plug in the values you know and solve for the ones you don't. So plug in 46 for the circumference and solve for the radius. (You'll get that the radius = (circumference)/(2pi)).
The radius of a circle when the numeric values of the circumference and the area are equal?
2 because the man said so
What is the radius of a circle if its circumference and area both equal 246?
A circle cannot have its circumference and area both equal to 246. The only possible equal values are circumference = 12.6 units area = 12.6 square units which are achieved by a circle with radius 2 units.
What is the diameter of a 9 inch circumference?
To find the diameter of a circle with a 9-inch circumference, you can use the formula for circumference: C = πd, where C is the circumference and d is the diameter. In this case, C = 9 inches. Rearranging the formula to solve for the diameter, you get d = C / π. Substituting in the known values, the diameter of a circle with a 9-inch circumference is approximately 2.87 inches.
What does circumference mean math term?
Circumference refers to the size of something as given by the distance around it, e.g. the circumference of a circle is the distance around it, or its perimeter. The circumference of a circle can be used in the following formula to determine other values in a circle: C=2πr, or C=πd, where C is the circumference of the circle, r is the radius of the circle, d is the diameter of the circle and equivalent to twice the radius, and pi is, well, pi.
Who gave values for pi?
Nobody because its a natural fact that the circumference of a circle divided by its diameter is always equal to pi.
When was the the circumference of the Earth first measured and by who?
One possible person is Eratosthenes of Cyrene ~230 BC as he was a Greek scientist who calculated the circumference of the Earth, with remarkable accuracy (some values for the "stadia" he used gives a result within 6% of the actual polar circumference). See link for further information
How do you do cercomference?
The circumference of a circle can be calculated using the formula C = 2 * π * r, where r is the radius of the circle. Or you can use C = π * d, where d is the diameter of the circle. Just plug in the values of r or d to find the circumference.
