Answer 1

Given :

• The radius of circle (r) = 49 cm

To find :

• The circumference of the circle

Solution :

★ We know:-

• Circumference = 2πr

→ Circumference = 2 × 22/7 × 49

→ Circumference = 44/7 × 49

→ Circumference = 44 × 7

→ Circumference = 308

Answer :

• The circumference of the circle = 308 cm
