Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
What is the Circumference of a circle whose diameter is 56cm?
circumference = pi*56 = 175.929 cm to 3 dp
How do you find the diameter of a circle with the perimeter?
The equivalent of a "perimeter" in a circle is actually called its circumference. To get the diameter, just divide the circumference by pi.
Is 56cm more than 6m?
No, 56cm is not more than 6m because 56cm < 6m. Notes: 1. Clarify the question "Is 56cm or than 6m?" to "Is 56cm more than 6m?" 2. Convert 56cm to meters (56 * 1/100 = .56m 3. Compare .56m to 6m: .56m < 6m 4. Answer the question: "No, 56cm is not more than 6m." ====== Answer 1: No. 6m= 600cm so 6m is greater than 56cm
What is difference between a radius and a diameter?
Radius is the shortest distance via straight line between the center point of the circle and its perimeter. Diameter is the greatest distance via straight line from one perimeter of the circle to the opposite perimeter. Diameter = 2x Radius.
