Perimeter = pi*diameter = 113.1 cm
Multiply the diameter by pi.
You get 2 circles of diameter. If you were trying to find a perimeter, Never double the diameter. If you have a radius, You have to double it to get a perimeter.
Its perimeter is half of its circumference plus its diameter
-- 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).
The equivalent of a "perimeter" in a circle is actually called its circumference. To get the diameter, just divide the circumference by pi.
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
Pi times the diameter gives you the circumference. Then divide that answer by two. Then add in the diameter - and, voila, you have your answer as to the perimeter of a semicircle.
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
It is its diameter plus half of its circumference
Diameter is "through", not "around". To find the perimeter ("around"), add the length of the six sides.
The formula for finding the perimeter (circumference) of a circle based on its diameter is C = πd. so if the diameter is 700m, you multiply that by π (3.14) for a circumference of 2,198m.
