area of a circle is pi x radius^2 so... pi x 4^2 = about 50 cm
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.
It is: 16*pi square cm
The 'best' estimate of the area of a circle with a radius of 7.62 meters is: 182.414692 m2
Area of a circle = pi multiplied by (radius squared)Pi is approximately 3.141 so do r x r x 3.141
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
