The length (circumference) of the curved part of a semi-circle is pi times the radius (pi*R). If the diameter is given, then the semi-circle length is 1/2 (pi * x D) because the radius is 1/2 of the diameter.
(There are 2pi radians in a full circle.)
A closed shape formed from a semi-circle has a perimeter P = D + (pi * D / 2)
(diameter plus the curved part)

How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
How do you figure the perimeter of a semicircle if the the straight side is 36?
Consider the straight side as the diameter of a circle, find the circumference of the circle, calculate half the circumference and then add it to the diameter. circumference = pi x diameter = 3.14 x 36 = 113.04 perimeter of semicircle = 1/2 circumference + 36 = 56.52 + 36 = 92.52
What is the perimeter of a semicircle if the diameter is 8cm?
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.
What is the approximate circumference of a semicircle with a diameter of 64 meters?
401.92 m
What is the diameter of a semicircle?
In a semicircle, the diameter is the straight line. It is also equal to double the radius, and that property allows it to be used when calculating area and circumference.
How do find the circumference of a recttangle and semicircle put together?
If the semicircle is placed on 1 side of the rectangle:Find the total perimeter(circumference) of the side opposite to the one with the semicircle's base and the 2 sides perpendicular to the semicircle's base.The formula for circumference of a circle is 2πr.Thus for the semicircle we will take the circumference as πr.Find the sum of 1st and 2nd points. This is the final answer.
How do we find a perimeter of a semicircle?
It is its diameter plus half of its circumference
How do you find the circumference of a semicicle?
circumference of a semicircle = pi * diameter / 2 (pi multiplied by the diameter and divided by 2)
