How do you work out the perimeter of a third of a circle?
The circumference of a circle is pi times the diameter. If you want a third of that, divide by 3. (Pi is approximately 3.14) Then to get the perimeter add the diameter to the circumference of the 1/3 of the circle.
How do you find the perimeter of a circle with just the diameter?
the perimeter is 3 times as long as the diameter Example: if my diameter is 7 inches long my perimeter is 3 times as much so it is 21 inches long
How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
How do you find the perimeter from the diameter?
The perimeter or circumference of a circle = diameter times pi
What is the perimeter of a circle if the diameter is 20 ft?
The perimeter is the diameter times pi. So the perimeter is 20pi ft

What is perimeter in circle?
Pi (3.1415...) times the diameter of the circle = the perimeter

What is the perimeter of a circle and the diameter of a circle?
Circumference (perimeter) of a circle = pi x diameter Diameter of a circle is the straight line distance from one side to the other which passes through the centre of the circle.
How do you find the perimeter from the diameter?
The perimeter or circumference of a circle = diameter times pi
What is the equation to find the perimeter of a circle?
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
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).
How do you find the perimeter of a semi circle with a diameter of 12mm?
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
What is the perimeter of a circle if the diameter is 20 ft?
The perimeter is the diameter times pi. So the perimeter is 20pi ft
What is the perimeter of a circle whose circumference is 3cm and diameter 3cm?
The perimeter of a circle is its circumference and it is: 2*pi*radius or pi*diameter
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.
