1. 36 cm​

Answer 1

Answer:

A true friend is someone you can rely on regardless of the circumstances. While they may give you the advice you don't want to hear from time-to-time, a true friend will never lead you purposely down the wrong road. They tell you as it is while presenting the truth to make it easy for you to receive.

Answer 2

Solution :

Diameter of circle = 36 cm

Radius of circle = d/2 = 36/2 = 18 cm

We know that

★ Circumference of circle = 2πr

→ 2 × 22/7 × 18

→ 792/7

→ 113.14

∴ Circumference of circle is 113.14 cm
