Question

if a wire of 440 cm length is moulded in the form of a circle . find the area of the circle​

Answer 1

Step-by-step explanation:

if a wire is being moulded to a circular ring

means length of wire = circumference of circle

now 440= 2πr

2×3.14×r= 440

r (radius)= 70 cm

now

area of circle = πr²

= 3.14× 70²

= 15386 cm²
