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.

What happens to the circumference of a circle when the radius is quadrupled?
It gets bigger.
What is the circumference of circle with radius 12cm?
The circumference of circle with radius 12cm is 75.4cm
What is the radius of a circle with a circumference of 110?
The radius of a circle with a circumference of 110 is: 17.507
What is the circumference of a circle with a radius of 6.7?
The circumference of a circle with a radius of 6.7 is: 42.097
What is the circumference of a circle if its radius is 3?
The circumference of a circle if its radius is 3 is about 18.85
What happens if a circle's radius is tripled?
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.
If you triple the radius of a circle how is its circumference affected?
The circumference of a circle = 2*pi*r. if you triple r, the circumference is tripled also.
What happens to the area of a circle if the radius is tripled?
The circle becomes an oval
What happens to the diamenter of a circle if you triple the radius?
It will be twice the size of the tripled radius
If area of a circle is tripled what haappens to the circumference?
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.
What happens to the circumference of a circle when the radius doubles?
If the radius of a circle doubles, the circumference doubles, and so does the diameter.
As the diameter of the circle increases what happens to the circumference?
The circumference of a circle increases with an increase in the radius as it is directly proportional its radius.
When the radius of a circleis tripled what happens to the circumference and the area of the circle?
Circumference(C) = 2πr C is directly proportional to r. If radius is tripled then circumference becomes three times of the initial. Since the radius is tripled so the new radius is 3r. New circumference(C') = 2π(3r) = 3 x (2πr) = 3 x C Area = πr2 A is directly proportional to r2. If radius is tripled then area becomes 9{square of 3} times of the initial. New radius is 3r. New Area(A') = π (3r)2 = 9 x π r2 = 9 x A.
What happens to the circumference of a circle if you double the radius?
The circumference also doubles.
What happens to the circumference of a circle when the radius is doubles?
The circumference also doubles.
What happens to the circumference of a circle when the radius is quadrupled?
It gets bigger.
What happens to the circumference of a circle when its radius is cut in half?
It splits
