Question

Solve for the Circumference if the diameter is 9 cm. Use the formula C= πd​

Answer 1

Answer:

28.28

Step-by-step explanation:

Circumference = πd (π×d)

here d (diameter) = 9 cm

so circumference = π×9 cm

= 22/7 × 9 cm

= 22×9/7 cm

= 198/7 cm

= 28.28 cm (approx)

Hence Circumference of circle = 28.28 cm.

note :- we have used the value of π = 22/7, sometimes we also use the value as 3.14

hope it helps.
