If you triple the radius of a circle what happens to the area?
The result is 9 time the original.
When the radius of a circle is tripled what happens to the perimeter and area of the circle?
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.
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
What happens to a circle when the radius is doubled?
The area quadruples.
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 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.
