Suppose the radius of the circle is r units.
Then perimeter of a whole circle = 2*pi*r.
So perimeter of curved part (arc) of a quarter circle = 2*pi*r / 4 = pi*r/2
Also, the quadrant has a radius on either end of the curved part. Their combined length is 2*r
So the total perimeter = 2r + pi*r/2 = r(2 + pi/4)

What is the formula of a perimeter of a circle?
to find the perimeter of a circle you simply do this (pi x D )
What is formula of perimeter of semi circle?
The perimeter of a circle has the formula 2πr. Therefore the length of a semi circle is πr. But the perimeter of a semi circle also includes the diameter which is 2r. Therefore the perimeter of a semi circle = πr + 2r = r(π + 2)
What is the formula of the sector of the circle?
There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
What is the formula for perimeter is shape is a circle?
The perimeter is equal to Pi times the diameter.
What is the perimeter of quarter circle?
The arc is one quarter of a circle so is 2pir, the other components of the quarter circle are the two radii, so perimeter is 2r+2pir = 2r(1+pi)
What is formula of perimeter of semi circle?
The perimeter of a circle has the formula 2πr. Therefore the length of a semi circle is πr. But the perimeter of a semi circle also includes the diameter which is 2r. Therefore the perimeter of a semi circle = πr + 2r = r(π + 2)
What is the formula of a perimeter of a circle?
to find the perimeter of a circle you simply do this (pi x D )
What is the perimeter of a three quarter circle?
I believe 270 because a circle's perimeter is 360 so if you divide it by 0.75, you get 270.
What is the formula of the sector of the circle?
There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
What is the formula for perimeter is shape is a circle?
The perimeter is equal to Pi times the diameter.
What is the formula for equillateral triangle?
There are different formula for: Height, Area, Perimeter, Angle, Length of Median Radius of inscribed circle Perimeter of inscribed circle Area of inscribed circle etc.
What is the formula for circle segment?
The answer will depend on what the formula is for: the perimeter or area of the segment.
Formula for perimeter of a circle?
Circumference or perimeter = 2*pi*radius or pi*diameter
How do you find perimeter of half circle?
The formula for the perimeter of a whole circle is 2 π r therefore the perimeter of a half circle will be (2 π r)/2 which is π r n.b. the perimeter of a circle is normally referred to as the circumference...
How do you calculate the perimeter of a semi circle?
The perimater of a circle is the same as the circumference of a circle, but if it's only a half of a circle (semi-circle) you would use the formula 2*pi*r/2 If it's a quarter of a whole circle, or a fifth of a circle, then you would divide it by 4 or 5.
