The circumference of a circle with radius of 10cm is: 62.83 cm
It is half of a circle; the circle's radius (and that of the semicircle) is 10 cm.
A circle of radius 10cm has a circumference of 2πr cm = 2π x 10 = 62.83 cmIf the diameter equalled 10cm then the radius equalled 5 cm and the circumference of this circle = 2π x 5 = 31.42 cm
Total SA = 1,256.6 cm2
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 is 314 cm2
314.2 square cm
The circumference of a circle with radius of 10cm is: 62.83 cm
Using 3.14 as Pi the area of circle is: 314.0
