Question

wire in the form of a rectangle 18.7 cm long and 14.3 cm wide is reshaped and bent into the form of a circle. Find the radius of the circle so formed.

Answer 1

Step-by-step explanation:

circumference = Perimeter of rectangle

2πr = 2(l + b)

πr. = L +b

( 22/7)r = (18.7+14.3) cm

(22/7)r. = 33cm

22r. = 33 *7 cm

r. = 33 * 7/22 cm

= 21/2 cn

= 10.5 cm
