Answer

ANS--D

Total length of the wire = 66*3 cm = 198 cm .

So, circumference of the circle = 198 cm. So, radius of the circle = 198/(2*pi) cm = 31.5 cm

Hence, area of the circle = pi*(31.5)^2 cm^2 = 3118.5 cm^2

Answer

Ans. Option D .

ATP, Total length of the wire = 66*3 cm = 198 cm .

So, circumference of the circle = 198 cm. So, radius of the circle = 198/(2*pi) cm = 31.5 cm

Hence, area of the circle = pi*(31.5)^2 cm^2 = 3118.5 cm^2 .
