Step-by-step explanation:
● Given :
☆ Length Of Wire = 60cm
☆ Pi as = 3
● To Find :
☆ Radius = ?
☆ Area = ?
● Solution :
》 The long wire is turned in this way that it make a circle...
》 So, Length of wire becomes Circumference of the circle...
》 2πr = 60cm
》 πr = 30
》 r = 30/π
》 r = 30/3. .......[ pi = 3]
》 r = 10
■ Radius = 10 cm
So, Radius Of Circle = 10cm
□ Area of circle = πr²
= π x 10 x 10
= 3 x 100
= 300 cm²
■ Area = 300cm²
