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 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.
If the base of a semicircle is a feet What is its perimeter?
The circumference of a circle = 2π r = π a (where a is the base of the semicircle and is also the diameter of the circle) The perimeter of the semicircle = half the perimeter of the circle + the base length The perimeter of the semicircle = πa/2 + a = a(1 + π /2) feet
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)
How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
What is the approximate circumference of a semicircle with a radius of 30 centimeters?
You can multiply the radius by pi to get the length of the semicircle.
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

10
How do you find the perimeter of a semicircle?
The circumference of a semicircle is pi times the radius plus the diameter.
What is the circumference of 52 m semicircle?
circumference or perimeter of the semi-circle = (diameter*pi)/2 + diameter
What is the approximate circumference of a semicircle with a diameter of 64 meters?
401.92 m
If the circumference of the circle is 20 cm what is the length of the thick semicircle?
10
What is a circle equal to one half of a circumference?
It is a semicircle.
