WebbThe radius of a circle or sphere is defined as the line segment that has one endpoint at the center of the circle and the second endpoint at the circumference. The outer boundary … WebbThe outer boundary, of this figure, is made up of semicircles. Diameter of each semicircle is 14 cm. We know that: Circumference of the circle = πd Circumference of the semicircle = `1/2`πd = `1/2 xx 22/7` × 14 cm = 22 cm. Circumference of each of the semicircles is 22 cm. Therefore, perimeter of the given figure = 4 × 22 cm = 88 cm.

WebbThe space enclosed by the boundary of the circle is termed as the area of the circle. • Secant: It is a line which intersects the circle in two points on the boundary. ... Let R and r be the outer and inner radii of ring. Then 2πr = 440 …(inner ring) 2 × (22/7) x r = 440 ∴ r = (440× 7)/(2 × 22) ∴ r = 70 m and impose rigorous
