Question

find the radius of a circle and its area if its circumference is 176 cm​

Answer 1

Answer:

The radius of the circle is ,28 cm

Step-by-step explanation:

Circumference (C) of the circle is given by

C=2πr ...... (1)

Where r is radius of the circle.

As Per The Statement :

Circumference of the circle is 176 cm . Therefore,

$c = 176$

Substitute (1),

$176 = 2\pi \: r$

$176 = 2 \times \frac{22}{7} \times r$

176 is divided by 2 so,

$r = 88 \times \frac{7}{22}$

then 88 is divided by 22 ,hence

$r = 4 \times 7$

$therefore \: =$

$r = 28cm$
