Question

If the circumference of a circle is 33cm, find its diam

Answer 1

We have the circumference of the given circle is 33cm. We know that the circumference of a circle is equal to 2 ×pi ×radius.

But,

33cm = 2×pi×radius

=7 × 33 /2 ×22 = radius

radius =5.25cm

Then, diameter is equal to twice radius

that is,

= (2× 5.25)cm = 10.5cm
