Question

Taking π=3.14. Find the perimeter and of a circle whose radis is 20​

Answer 1

Answer:

Step-by-step explanation:

→ π= 3.14

→ Radius of circle = 20 cm

→ Perimeter of circle = 2πr

→ Perimeter = 2 × 3.14 × 20

                 = 6.28 × 20

                 = 125.60 cm

→ perimeter of circle of radius 20 cm is 125.60 cm
