Given :

  • Radius, r = 7 cm

To find out:

Find the perimeter ( circumference ) and area of the circle?

Formula used:

  • Area of circle = πr²

  • Perimeter of circle = 2πr

Solution:

★ Area of circle = πr²

= 22/7 × 7²

= 22/7 × 49

= 22 × 7

= 154 cm²

★Perimeter of circle = 2πr

= 2 × 22/7 × 7

= 2 × 22

= 44 cm
