C1 = pi x D, C2 = pi x 3 x D, so the circumference is also tripled.
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).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
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.
It will make the circumference of the circle bigger or smaller
The circumference also doubles.
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.
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
The circumference of a circle = 2*pi*r. if you triple r, the circumference is tripled also.
