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.
A circle with a radius of 2.5 meters has an area of 19.63 square meters.
Area = p* r2 628 ft2 = pi*r2 divide both sides by pi, which is the coefficient of r2 199.8986 = r2 Take square root each side 14.1 feet = radius =============
The height of a cylinder with lateral area of 628 and radius 2.5 is approximately 39.98 units.
circumference (C) = 2piR = Two x Pi x Radius Pi = 3.14.... R= C/2pi if C = 628 R = 628/ 2 (3.14...) R= 99.949 cm
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
If the area of a circle is 40.7 the radius is: about 3.6 (3.599)
