39.	Radius (r) Diameter (d) Circumference (c) Sr. No.(i)7 cm28 cm616 cm72.6 cm(iv)
Answer» 11.55 cmStep-by-step explanation:i. Radius (r) = 7 cm Diameter (d) = 2r = 2 x 7 = 14 cm Circumference (C) = πd = 22/7 x 14 = 44 cm ii. Diameter (d) = 28 cm Radius (r) = d/2 = 28/2 = 14 cm Circumference (c) = πd = 22/7 x 28 = 88 cm iii. Circumference (c) = 616 cm ∴ πd = 616 ∴ 22/7 x d = 616 ∴ d = 616 x 7/22 ∴ d = 196 cm ∴ Diameter (d) = 196 cm Radius (r) = d/2 = 196/2 = 98 cm iv. Circumference (c) = 72.6 cm ∴ πd = 72.6 ∴ 22/7 x d = 72.6 ∴ d = 72.6 x 7/22 = 726/10 x 7/22 = (33 x 7)/10 ∴ d = 23.1 cm ∴ Diameter (d) = 23.1 cm Radius (r) = d/2 = 23.1/2 = 11.55 cm
