The formula for finding the area of a circle is : pi(r) squared. So, that answer would be 13.69cm multiplied by pi, which is nearest to 3.14.
The area of a circle is 153.86cm².find the radius of the circle
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.
A circle with a radius of 4 cm has an area of 50.27 square cm.
The area of a circle with a radius of 7 cm is: 153.9 cm2
The area of any circle is (pi) x (radius)2 .The area of half the circle is just half of that number.
The area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
The area of a circle with a radius of 14.4 is 651.4
A circle with a radius of 135 units has an area of 57,255.53 square units.
A circle with a radius of 10m has an area of 314.16 m2
The area of a circle with a radius of 2m is: 12.566 m2
The radius of a circle when the area is 96 is 5.528
The area of a circle if the radius is 7yd is 153.9yd2
If the area of a circle is 40.7 the radius is: about 3.6 (3.599)
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
