Question:-
The diameter of a circle is 18 m. Find its circumference in terms of π.
Solution:-
Diameter of a circle = 18 m. (Given)
Radius (r) of a circle = 18/2 = 9 m.
We know,
So, It’s circumference is (2 × π × 9) m.
It’s circumference is 18π m.
It’s circumference in terms of π is 18π m. [Answer]
Answer:
The circumference of a circle =πd = π×18 =18π m
