A circle is a curve sketched out by a point moving in a plane. The area of the sector PQR is 41.346 units².
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
Given the radius of the circle is 8 units, while the angle of the sector is 74°. Therefore, the area of the sector is,
Area of the sector = π×R²×(74/360)
= π × 8² × 0.20556
= 41.346 units²
Hence, the area of the sector PQR is 41.346 units².
