If the diameter of the circle is 5 cm then its circumference is: 5*pi cm
The circumference of a 5 cm circle is: 15.71 cm(diameter x pi = circumference).
The circumference of a circle can be calculated using the formula C = ฯd, where C is the circumference, ฯ is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 5 cm, so the circumference would be C = ฯ * 5 cm = 15.70796 cm.
Pi times the diameter of a circle gives its circumference. Since the radius is 5 cm, the diameter is 10 cm, and pi x 10 cm is the answer, or 31.4159 cm.
The formula for circumference is pi x d, so the circumference is 15.7 cm.
The formula for circumference is pi x d, so the circumference is 15.7 cm.
Circumference of a circle is 2*pi*radius or pi*diameter. Therefor, if the circumference of the table is 15.7 cm then its diameter is 15.7/pi = 4.9975 cm or roughly 5 cm. So the circumferences and diameters of the table and its leg are equal.
Well, first of all, it has to be a circle or a sphere, otherwise it's perimeter, not circumference. But if your object is a circle or a sphere, the formula is C=pi x diameter. So the circumference of your object is 5pi
The circumference of a circle with diameter D is πD where π = 3.14159 approx. So D = 5 gives a circumference of 15.7 cm
Area = pi*2.52 = 19.63495408 or about 20 square cm Circumference = pi*5 = 15.70796327 or about 16 cm
A circle of radius 10cm has a circumference of 2πr cm = 2π x 10 = 62.83 cmIf the diameter equalled 10cm then the radius equalled 5 cm and the circumference of this circle = 2π x 5 = 31.42 cm
circumference = 5*pi = 15.70796327 or 15.708 cm rounded to 3 d.p.
