Area = pi*r2 = 78.5 mm2
The radius would be 2.5 mm.
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 circumference of a circle, if the radius is 5mm, is about 31.42mm
The radius would be 2.5 mm.
The area of a circle 1cm in diameter is determined by the formula Pi x Radius x Radius. Radius is 5mm Pi is 3.14159 (roughly) So the area is 3.14159 x 5 x 5 Which is 78.5398163397448 square mm.
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
