The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
The circumference of any circle is (pi) x (the circle's diameter).
The circumference of a circle, if the diameter is 9.5 inches, is: 29.85 inches (diameter x Pi = circumference)
The diameter of a circle with circumference of 25.56 inches is: 8.136 inches (diameter x Pi = circumference).
The circumference is doubled or tripled, respectively.
9 times bigger
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
When you double the diameter, the circumference is also doubled.
Since the equation for circumference is pi*d then if you double the diameter the circumference will be doubled.
The circumference also doubles.
It will make the circumference of the circle bigger or smaller
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The formula for the area of a circle is, A = πr2 If the area is tripled then the larger circle has an area of A2 = πR2 (where R is the new radius) But, πR2 = 3πr2 : R2 = 3r2 : R = r√3 The circumference of the original circle was 2πr. The circumference of the larger circle is 2πR = 2πr√3 Therefore, if the area is tripled, then the circumference increases by √3.
