The radius is directly related to the circumference of a circle by C=π 2R so it would get proportionately larger as the circumference grows.
If you start with C=π 2R where 2R=C/π then change C to C2=3C then 2R2 becomes C2/π or 3(2R)/π

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

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

# If you triple the radius of a circle how is its circumference affected?

The circumference of a circle = 2*pi*r. \n. \nif you triple r, the circumference is tripled also.

# What happens to the radius of a circle when the diameter triples?

The radius becomes one and a half times larger

# What if you triple the diameter of a circle what happens to the circumference?

The circumference is tripled. C=pi*d, so pi*(3d) = 3C, where d is diameter and C is circumference.

# Is the circumference of a circle is tripled what happens to its radius?

The radius is tripled, too. Suppose: (1) C = 2Ïr (2) C' = 2Ïr' (3) C' = 3C Then C' = 3(2Ïr) = 2Ï(3r) But C' = 2Ïr', so 2Ïr' = 2Ï(3r)

# If the radius of a circle is tripled what happens to the circumference?

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

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

The circle becomes an oval

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

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

# What happens if you triple the radius of a circle?

If you triple the radius of a circle . . . -- You should not expect anything to happen. Those around are likely to remain completely unaware that you have done anything to yo

# What happens to the area of a circle if you triple a radius?

When you triple the radius of the circle . . . -- The diameter also triples. -- The circumference also triples. -- The area is multiplied by 9 .

# What happens if you triple the radius in a circle?

nothing you will just just get the radius in 3 circles.

# What happens to the circumference of a circle if you triple the radius?

Since circumference is proportional to the diameter (the proportionality is the definition of the irrational number pi) and the radius is just twice the diameter, if you tripl

# What happens to the diamenter of a circle if you triple the radius?

It will be twice the size of the tripled radius

# What happen to the area of circle when the radius is triple?

The area increases to nine times the original area.

# What happens to the area of a circle when you triple the radius?

As the area of a circle is pi*radius 2 the increase in area is a factor of 3 2 . So tripling the radius gives an increase in area by a factor of 9.

It would triple
