reshaped and bent in the form of circle, find the radius and the area of the circle​

Answer 1

Answer:

Given length of rectangular wire = 18.7 cm Breadth of rectangular wire = 14.3 cm According to the question length of wire = circumference of the circle = 2 (l + b) = 2 × (18.7 + 14.3) = 2 (33) = 66 cm Let the wire bent in the form of circle of radius r cm then we have Circumference = 66 cm 2 π r = 66 2 × (22/7) × r = 66 44/7 r = 66 r = (66 × 7)/44 r = 462/44 = 10.5 cmRead more on Sarthaks.com - https://www.sarthaks.com/690637/wire-the-form-rectangle-18-cm-long-and-14-cm-wide-is-reshaped-and-bent-into-the-form-of-circle?show=690638#a690638
