2 \times \frac{22}{7} \times \frac{28}{10} 2×7

22 × 10

28\frac{22 \times 2 \times 4}{10}

22×2×4

10\frac{176}{10}

Step-by-step explanation:

Diameter of the circle = 5.6 Cm

Radius of the circle = 5.6/2 = 2.8 Cm

Formula to find the circumference of a circle = 2πR

Value of π (pi) = 3.14

Circumference of the circle = 2πR

= 2 X 3.14 X 8

= 17.59292 Cm
