Circumference = 2*pi*r
r = diameter/2
20/2 = 10
------------------so,
2*pi(10)
= 63

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)
If the circumference of the circle is 20 cm what is the length of the thick semicircle?
10
What is the formula for the perimeter of a semicircle?
If you are given the diameter 'D' of the circle: the full circumference is (pi times D) the perimeter of the semicircle is half this plus the diameter Therefore: Pi x D /2 + D
What is the circumference of a circle with a diameter of 20 centimeters?
The circumference of a circle with a diameter of 20 centimeters is: 62.83 cm (diameter x Pi = circumference).
If the circumference of a circle is 20 feet what is the diameter?
If the circumference of a circle is 20 feet the diameter is: 6.366 feet (circumference divided by pi = diameter).
What is the circumference of 52 m semicircle?
circumference or perimeter of the semi-circle = (diameter*pi)/2 + diameter
What would the perimeter of a 20ft semicircle be?
That depends on what you mean by a "20 ft semicircle".A semi-circle is a half circle.A 20 ft circle could be:A circle of diameter 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe perimeter of the semicircle is half the circumference plus double the radius → perimeter = 1/2 2π 20 ft + 2 x 20 ft= 20π + 40 ft≈ 102.08 ftA circle of circumference 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2 20 ft + 20 ft ÷ π= 10 ft + 20/π ft≈ 16.37 ftHowever, if a 20 ft circle is a circle with a circumference (= perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle with a perimeter of 20 ft→ perimeter = 20 ft
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 we find a perimeter of a semicircle?
It is its diameter plus half of its circumference
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.
What is the approximate circumference of a semicircle with a diameter of 64 meters?
401.92 m
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
How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
What is the perimeter of a semicircle with 28mm as diameter?
Perimeter (or circumference) of a circle = pi x diameter = pi x 28, but we need the circumference of only half of it (semicircle is half of a circle) Hence the answer is pi x 14 = 3.1415 x 14 = 43.981 mm
If the circumference of the circle is 20 cm what is the length of the thick semicircle?
10
What is the formula for the perimeter of a semicircle?
If you are given the diameter 'D' of the circle: the full circumference is (pi times D) the perimeter of the semicircle is half this plus the diameter Therefore: Pi x D /2 + D
What is the circumference of a circle if its diameter is 20 inches?
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
