The area of the circle becomes 9 times the area of the original circle.

Original circle = Pi * (r ^ 2) = Pi * r * r

New Circle = Pi * ((3 * r) ^ 2) = Pi * 9 * r * r

What happens to the area of a circle if the radius is tripled?

The circle becomes an oval


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.


When the radius of a circle is tripled what happens to the area?

It is increased nine fold. New Area = 9*old area.


What happens to the area of a circle when the radius is doubled tripled?

The area increases as the square of the radius (or diameter). So if you double the radius you * 4 (quadruple) the area. Treble the radius, you *9 the area.


What happen to the area of circle when the radius is tripled?

If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the 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.


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.


When the diameter of a circle is tripled what happens to the area of the cirlcle?

Area is proportional to the square of the linear dimensions.If diameter is tripled, area increases by a factor of (3)2 = 9 .


If the radius of a circle is doubled what happens to the area of the circle?

the area of the circle is increased by 400%


What happens to the area of a circle if yo double the radius?

Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same


When the radius of a circle is doubled what happens to the area?

It quadruples.


What happens to a circle when the radius is doubled?
