C = 2(pi)r 8cm=2(pi)r (8cm)/2pi = r d=2r d=8cm/pi
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
The circumference of 1.5 diameter is: 4.712
Circumference = Pi * diameter
Circumference = Diameter*pi So diameter = Circumference/pi = 32*pi/31 = 32
It has a circumference of 50.3cm
Circumference of a circle = 3.14 x d 3.14 x 8 = 25.12 Therefore the circumference of a circle with the diameter of 8cm is 25.12cm.
Circumference of a circle: 2*p*radius or pi*diameter
C = ~25.133 cm
It depends on the ratio of what of the circle? Its circumference, diameter, area?
C = 2(pi)r 8cm=2(pi)r (8cm)/2pi = r d=2r d=8cm/pi
To find the perimeter of a semicircle, you need to add the curved edge (half the circumference of a full circle) to the diameter of the semicircle. The formula for the circumference of a full circle is C = πd, where d is the diameter. Therefore, the circumference of the full circle is π(8) = 8π cm. The perimeter of the semicircle would be half of the circumference of the full circle plus the diameter, so it would be 4π + 8 cm, or approximately 20.28 cm.
It is 25.1 cm.

C=3.14*d<----diameter d=r*2 ex: what is the circumference of a circle if the radius is 4cm? 4*2=8cm 3.14*8=25.12cm c=25.12cm
A = 5.093 cm2
the answer is 20.54
