Want this question answered?
Circumference = 2*pi*radius So Radius = Circumference/(2*pi) = 8/(2*pi) = 4/pi = 1.2732 (to 4 dp)
The diameter = 2*r where r is the radius of the circle. So 16 = 2r. Therefore the radius = 16/2 = 8. The area of a circle = Pi*r^2 = Pi*(8)^2 = 64*Pi.
If the radius of a circle is 8 cm, the circumference will be: 50.3 cm (C = r x 2 x Pi).
8 divided by (2*pi) = a radius of 1.273239545 linear units
circumference of a circle = 2*pi*radius or diameter*pi
Circumference of a circle = 2*pi*radius = 8*pi or 25.13274123 units
Circumference of the circle: 2*pi*8 = 16*pi m
Area of circle: pi*8^2 = 64*pi square cm
Circumference = 2*pi*radius So Radius = Circumference/(2*pi) = 8/(2*pi) = 4/pi = 1.2732 (to 4 dp)
Radius of a circle = 1/2 of the diameter.Area of a circle = (pi) x (radius)2For the diameter of 16-ft, radius = 8-ft, and area = (pi) (8)2 = 201.062 square feet (rounded)
A circle with a radius of 8 units has a circumference of 50.27 units.The circumference will be 16 pi or 50.2655 (about). Circumference, the distance around a circle, is pi times diameter or it's pi times twice the radius.C = 2 * pi * r = 2 * pi * 8 = 16 * pi
The diameter = 2*r where r is the radius of the circle. So 16 = 2r. Therefore the radius = 16/2 = 8. The area of a circle = Pi*r^2 = Pi*(8)^2 = 64*Pi.
If the radius of a circle is 8 cm, the circumference will be: 50.3 cm (C = r x 2 x Pi).
64 pi
8 divided by (2*pi) = a radius of 1.273239545 linear units
It is: pi*82 = 64*pi square units
circumference of a circle = 2*pi*radius or diameter*pi
