Best Answer

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 your circle.

-- You wind up with a circle that's three times as big as it used to be.

-- The diameter of the circle is three times the original diameter.

-- The circumference of the circle is three times the original circumference.

-- The area of the circle is nine times the original area.

It will be twice the size of the tripled radius

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

The result is 9 time the original.

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 triple the radius, you also triple the circumference.

As the area of a circle is pi*radius2 the increase in area is a factor of 32. So tripling the radius gives an increase in area by a factor of 9.

It will be twice the size of the tripled radius

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

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 triple the radius, you also triple the circumference.

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.

As the area of a circle is pi*radius2 the increase in area is a factor of 32. So tripling the radius gives an increase in area by a factor of 9.

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

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

The perimeter would triple and the area would be multiplied by nine (32). Circumference (perimeter) is (2 x pi x r), so would be (6 x pi x r) for triple the radius, and area is (pi x r2), so would be (pi x 32 x r2) for triple the radius.

If the radius of a circle doubles, the circumference doubles, and so does the diameter.
