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.
What happens to the area of a circle when the diameter is halved?
It is reduced by a quarter. If you halve the you also halve the diameter The area (A) of a circle is = pi x (radius)squared. If you halve the radius and then square it then to balance the equation the area must be divided by Four.
What is a radius square?
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
What is the area of a circle with radius of 4cm?
A circle with a radius of 4 cm has an area of 50.27 square cm.
What is the area of a circle with a radius of 7 cm?
The area of a circle with a radius of 7 cm is: 153.9 cm2
If you triple the radius of a circle what happens to the area?
The result is 9 time the original.
What happens to the area of a circle when the radius is triple?
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 happens to the area of a circle when you triple the radius?
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.
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 the radius of a circle is doubled what happens to the area of the circle?
the area of the circle is increased by 400%
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 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 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 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.
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 doubled what happens to the area?
It quadruples.
What happens to a circle when the radius is doubled?
The area quadruples.
