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 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.
