How to find the length of the curved part of the semicircle?
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=2c=2πrc=2π2c=4πc=(approximately)12.5712.57 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 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.
A 30-inch segment is cut into two parts whose lengths have the ratio 3 to 5 Find the length of each part Does anyone know how to figure this out?
Divide 30 by 8 (5+3). Multiply the answer by 3 for the one part length and 5 for the other part length.
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 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)
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 get rid of curved nails?
by cutting the curved part.

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.

How can you find the ratio of a scale?
Divide any length of any part of one of the objects to the length of the corresponding part of the other object.
Curved part of the foot?
Arck
How do you imagine part of one curved face is contained by another curved face?
Get a ball. Draw any closed shape on it. The part inside the curve that you drew is one curved face and that is contained by the surface of the ball which is the other curved face.
