Question

The four maximum sized circular plates are cut out of a brass plate of square size.
Having the area 196 sq. cm. Calculate the circumference of each drcular plate
​

Answer 1

Step-by-step explanation:

2*22/7*r^2=196

r2=196*7/44

Answer 2

22 cm

Step-by-step explanation:

Area of square plate = 196cm^2

Side of square plate = √196cm^2

= 14cm

Now, 2× diameter of each circle = side of square

⇒2×2r = 14cm⇒r = 3.5cm

Circumference of circular plate = 2πr

= 2×22/7×3.5 cm

= 22 cm
