Area of a circle is pi times the radius squared.
Radius is 3 times as large so area is 3*3 = 9 times as large.
6
It becomes twice as large
The area of a circle is directly proportional to the square of its radius. If two circles have radii R1 and R2 , then the ratio of their areas is ( R1/R2 )2

Area of a circle = pi*radius2
Area of a circle = Pi * radius2
Area of a circle = pi*radius2
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
Using 3.14 as Pi the area of circle is: 0
the area of the circle is increased by 400%
