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.
How do you change area of a circle into radius?
Figure out the square root
If a radius of a circle is increased by 10 percent by what percent does its area increase?
area goes as radius squared 1.1 x 1.1 = 1.21 or 21%
What is the area of a circle with the radius of 21?
The area of a circle of radius 21 is 1386
What is the area of circle with a radius of 35?
Area of a circle = pi*radius squared
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 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.
The radius of a circle is multiplied by 7 Its area is times bigger than the original circle?
The relationship between a circle's radius and it's area is: a = πr2 so if the radius of the circle increases by 7 times, the area will increase by π72 times, or 49π, which is approximately equal to 153.938
