Question

the perimeter of a circle is 176cm find the radius
​

Answer 1

Given :-

Perimeter of Circle = 176 cm.

To Find :-

Radius :-

Formula Used Here :-

Perimeter of Circle = 2πr

Solution Start :-

$= > Perimeter \: of \: Circle = 2πr \\ \\ = > 176 \: cm = 2 \times \frac{22}{7} \times r \\ \\ = > 176 \: cm = \frac{44}{7} \times r \\ \\ = > \frac{176 \times 7}{44} = r \\ \\ = > \frac{\cancel {176} \times 7}{\cancel {44}} = r \\ \\ = > 4 \times 7 = r \\ \\ = > 28 \: cm \: = radius$
