Find the diameter of circle when its curcumference is given:i) 44cm(step by step explanation please)​

Answer»

Given:

Circumference of the circle = 44 cm

To Find:

The DIAMETER of the circle.

Formula:

Circumference of a circle = 2πr

where, π = pi and r = RADIUS of the circle

Explanation:

ACCORDING to the question,

2πr = 44

or, {\tt {\frac {22}{7} \times r = \frac{44}{<klux>2</klux>} = 22}}

or, {\tt { r = 22 \times \frac{7} {22} = 7 \: cm}}

ANSWER:

The radius of the circle is 7 cm.

The diameter will be 2(7) = 14 cm.

Therefore, the diameter of the circle is 14 cm.
