AnswEr :-

• Circumference of the circle is 30cm.

Given :-

• Diameter of a circle as 30cm.

To Find :-

• Circumference of the circle.

SoluTion :-

» Radius = Diameter/2

→ r = d/2

→ r = 30/2

→ r = 15cm

★ As we know that formula for finding circumference of the circle is :-

» Circumference = 2πr

→ 2 × 22/7 × 15

→ 660/7

→ 94.28cm

Hence, the circumference of the circle is 94.28cm.
