A wire in the form of a circle of radius 84 cm, is cut and bent in the form of a square. If pi is taken as 22/7, the side of the square (in cm) is:
A88
B110
C132
DNone of these
Answer:
C. 132
Read Explanation:
Length of wire = circumference of circle = 2πr
= 2 × 22/7 × 84 = 528 cm
Length of wire = Perimeter of square
528 = 4a
a = 528/4 =132 cm
Side of square = 132 cm
