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.
The area of a circle is 153.86cm².find the radius of the circle
Area of a circle = pi times radius squaredDiameter of a circle = 2 times radius
The area of a circle with a radius of 7 cm is: 153.9 cm2
A circle with a radius of 4 cm has an area of 50.27 square cm.
The height of a cylinder with lateral area of 628 and radius 2.5 is approximately 39.98 units.
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 =============
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 with a radius of 14.4 is 651.4
The area of a circle of radius 21 is 1386
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
Area of a circle = pi*radius squared
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)
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
