Question

if a circumference of a circle is 176 CM ,find its radius​

Answer 1

$2\pi \: r = 176$

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

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

$r = 28$

Answer 2

Step-by-step explanation:

Given,

circumference = 176cm

then, radius = ?

According to question we have,

C = 2pie R

176 = 2 × 22/7 × r

176 /2 = 22/7 ×r

88 × 7/22 = r

4 ×7 = r

This emplies r = 28cm

Hence, Radius of the circle = 28cm Ans....
