The circumference is doubled or tripled, respectively.
The circumference of a circle divided by its diameter is equal to the value of pi
The circumference is also quadrupled.
It quadruples.
The circumference also doubles.
The circumference is doubled or tripled, respectively.
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.
C1 = pi x D, C2 = pi x 3 x D, so the circumference is also tripled.
The circumference of a circle divided by its diameter is equal to the value of pi
The diameter of a circle is doubled if the circumference is doubled.
If the radius is tripled then the Area will be greater by a factor of 9. And the circumference will be greater by a factor of 3.
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 .
The circumference is also quadrupled.
It quadruples.
If you double the circumference. the diameter like wise would double.
The circumference also doubles.
If the radius of a circle doubles, the circumference doubles, and so does the diameter.
