A sector is created by the central angle formed with two radii, and it includes the area inside the circle from that center point to the circle itself. The added complexity comes from the need to calculate how much of a circle a sector accounts for. = π* 25 * 42 /180+2* 25. Thus the perimeter of the sector is r+θr+r. The perimeter of a sector of a circle of radius 5.2cm is 16.4cm. Therefore, by factoring out the r we get the formula P=(2+θ)r. Plug in the perimeter of 32 for P and we get 32=(2+θ)r. The line "and an area of 63cmsquare" is talking about the area of the sector we just outlined. so the formula for finding perimeter of angle 60 degree = length of arc +2*radius so the perimeter will be =(x/360°) 2 πr + 2r By putting the values we will got = (60 ° /360 °)( 2 *3.14 * 10.5) + 2* 10.5 So upon solving the perimeter of sector will be = 32 cm. The curved part of the sector is of the circumference of the circle but to find the perimeter of the sector we must add (the radius of the circle is) so the perimeter of the sector is. θ 360 * 2 π (r) + 2 r That would be the length of … The most common sector of a circle is a semi-circle which represents half of a circle. The Corbettmaths Practice Questions on the Area of a Sector. So the area of the sector is this fraction multiplied by the total area of the circle. By substituting the above given data in the previous function; (i.e.) A circle containing a sector can be further divided into two regions known as a Major Sector and a Minor Sector. (2) Given that r = 2√2 and that P = A, (b) show that θ = 2 1 The angle subtended at the center of the circle by the arc is called the central angle.

Sector of a circle ↺ Theta is an angle that can be defined as the figure formed by two rays meeting at a common endpoint. The total area of a circle is πR 2 corresponding to an angle of 2π radians for the full circle. Area of a sector formula. The formula for the area of a sector is (angle / 360) x π x radius 2.The figure below illustrates the measurement: As you can easily see, it is quite similar to that of a circle, but modified to account for the fact that a sector is just a part of a circle. Let the angle subtended by the arc of the sector at the centre of the circle (radius assumed to be [math]r[/math]) be [math]\theta[/math]. The perimeter of the sector is P cm and the area of the sector is A cm. Or P = d + L ( arc) => P = 2r + {(β*2 pi r)/360°} , where β is sector angle. The formula for the perimeter of a sector is 2 x radius + radius x angle x (π / 360). Visual on the figure below: A sector is just a part of a circle, so the formula is similar. Units Metric units. Find A(P-abc).

The sector to the right is a fraction of the circle to the left so the the area of the sector is. The perimeter of the sector includes the length of the radius $\times 2$, as well as the arc length.So the perimeter is the length "around" the entire sector, the length "around" a slice of pizza, which includes it's edges and its curved arc.. These units are related as follows: 10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km The word 'perimeter' is also sometimes used instead of circumference.
