WebMar 21, 2024 · Radius: A line segment joining the center of a circle to any location on the circle itself is called the radius of a circle. Diameter: A line segment whose both endpoints are on the circle and is the largest chord of the circle is called the diameter of a circle. Annulus: The area bounded by two concentric circles is called the annulus. WebDefinition of a Semicircle: When an arc of a circle with its endpoints on the diameter cuts a circle into two equal halves, those halves are called semicircles. It is the most common shape we find in real life, for example, the shape of the protractor, speedometer, taco, and so on. The image below represents a semicircle PQR along with the arc ...

Solution: Given; Radius of the circle = 4cm. Arc angle=π/8. The arc angle is in radians thus, Using the arc length formula i.e. = L = θ x r. L = π 8 × 4.
WebFeb 28, 2024 · The radius of a circle is defined as the distance measured from the centre of the circle to any point on its circumference. A circle is defined as a two-dimensional shape, which occupies its area and perimeter. For any circle in mathematics, the common notation used to denote the radius is ‘R’ or ‘r’.
