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)

I believe 270 because a circle's perimeter is 360 so if you divide it by 0.75, you get 270.

There is no such thing as the perimeter of a circle. The circumference, however, is 12.4*pi (since the formula is pi*diameter)

The perimeter is also known as the circumference of a circle.

There are different formulae for the perimeter, area or other aspects of each shape. Furthermore, the formula may well depend on what information is available to you.

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)

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)

to find the perimeter of a circle you simply do this (pi x D )

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)

I believe 270 because a circle's perimeter is 360 so if you divide it by 0.75, you get 270.

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.

The formula for the circumference of a circle is pi * diameter or (2 radius.)

The perimeter is equal to Pi times the diameter.

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.

The answer will depend on what the formula is for: the perimeter or area of the segment.

Circumference or perimeter = 2*pi*radius or pi*diameter

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...
