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!

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.
A rod of length L has total charge Q distributed uniformly along its length it's then bent in the shape of a semicircle find the magnitude of the electric field at the centre of semicircle?
At the center of the semicircle, the electric field due to the straight part of the rod will cancel out because of the symmetry. The electric field at the center of the semicircle is only due to the curved part, so you can treat the semicircle as an arc of a circle with charge distributed along its length. You can then calculate the electric field using the formula for the electric field of a charged arc of a circle.
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
What shape has one curved side and 2 straight sides?
The shape that has one curved side and two straight sides is a semicircle. A semicircle is a two-dimensional shape that is half of a circle, with one curved side and two straight sides that connect at the endpoints of the curved side. The curved side of a semicircle is a semicircular arc, while the two straight sides are diameters that intersect at the center of the circle from which the semicircle is derived.
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.
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.
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."
