A circle is two semicircles put together. The circumference of a circle is the length around it, so half of that would be what you are aiming for. Let's call the circumference "c" and the radius (the straight part of the semicircle) "r". Pi is also needed in this problem, so we can use "π". The equation for the circumference of a circle is c=2πr. Replace "r" with the length of the straight part of the circle, and do the math. Divide your answer by 2.
Example:
r=2
c=2πr
c=2π2
c=4π
c=(approximately)12.57
12.57 divided by 2 equals approximately 6.29.
The length of the curved part of the semicircle is 6.29!
Hope this helps!

How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
How do you find the length of the curved part of the quartercircle?
Work out the circumference of the circle and then divide it by 4
How do you find the arc in a sector?
If it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.
What does it mean for a straight line such as a radius to be equal in length to a curved line such as an arc of a circle?
Length of any curve is imagined as an infinite sum of the lengths of infinitely small straight sections. If you look at a part of circle under a microscope you cannot tell that it is curved. This idea is used extensively in the branch of mathematics call "integral calculus". On a practical level, you can lay out a circle with a length of wire, then straighten it out to measure its length.
Is the optical axis parallel to the curved surface?
No. It's straight through the center of the sphere that the curved surface is part of.
How do you find the circumference of a half circle if you have the diameter?
The length of the curved part of the semicicle is π*d/2 where π is the transcendental number approximated by 3.14159 and d is the diameter. The length of the straight part of the semicircle is, of course, d.
How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
How do you find the length of the curved part of the quartercircle?

What is the equation for the Surface Area of a cylinder?
If the cylinder has radius R and length L , the curved part of the surface has area 2piRL and each of the ends has area piR^2. The total surface area is the sum of the curved part plus two ends.
How do you find the circumference of a semi-circle?
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)
Where does the word semicircle get its name?
Semi means part of. So semi circle is part of a circle.
How do you get rid of curved nails?
by cutting the curved part.
Was not part of a caravel?
curved keel
What is the name given to the curved part of the saddle?
The curved part of a saddle is called the "seat."
How do you find the arc in a sector?
If it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.
What is the top part of a circle?
half a circle is a semicircle half a ball is a hemisphere does that help?
