12. The circumference of a circle is 31.4 cm. Find the radius and the area of the circler
(Take 7 = 3.14)​

Answer 1

Step-by-step explanation:

GIVEN

• Radius of circle=2 cm

• Side of aluminium square sheet=6 cm

According to question

• Area of aluminium sheet left=Total area of aluminium sheet−Area of circle

Solution

• side × side − πr^2

• 6 * 6 - 22/7 * 2 * 2

• 36 − 12.56

• 23.44cm^2.

Therefore, the area of aluminium sheet left is 23.44cm^2.
