Answer 1

Given :- draw a circle with radius 4.5 cm on it mark and name (a) the centre (b) a radius (c) a diameter (d) an arc (e) chord (f) the circumference (g) point R,S and T in the interior of the circle (h) point L,M and N in the exterior of the circle ?

Solution :-

from image we have :-

• O = centre of circle.
• OA = OB = radius of circle => 4.5 cm.
• AB = Diameter of circle => radius * 2 = 4.5 * 2 = 9 cm.
• AC = chord .
• AC = Minor arc . { Arrow mentioned . }
• point R,S and T in the interior of the circle .
• point L,M and N in the exterior of the circle .
• Circumference = complete outside length of circle.
