i don't know i think you should just try your best
Multiply the diameter by the value of Pi - and you'll have your answer !
8cm. The radius is always half the diameter.
The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.
The diameter would be 8cm, because the diameter is always double the radius. That's why the formula 2'Pi'r is also known as 'Pi'd.
What is the perimeter of a three Quarter with 3m radius
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.
The diameter of a circle may found by dividing the circumference by pi. 8cm/3.1416=2.546cm
Multiply the diameter by the value of Pi - and you'll have your answer !
C = ~25.133 cm
It depends on the ratio of what of the circle? Its circumference, diameter, area?
radius=4cm diameter=8cm *radius is half the diameter
Circumference of a circle: 2*p*radius or pi*diameter
8cm. The radius is always half the diameter.

The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.
Since diameter is 2 x pi x radius, 8 cm / 2 / 3.14 is about 1.3cm. Specifically, 1.2732cm.
The diameter would be 8cm, because the diameter is always double the radius. That's why the formula 2'Pi'r is also known as 'Pi'd.
