Find the diameter of circle whose circumference is 176 cm​

Answer 1

Question:-

Find the diameter of circle whose circumference is 176 cm

Answer:-

$circumference = 2 \: \pi \: r$

$2 \: \pi \: r \: = 176$

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

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

$r = \frac{1232}{44}$

$r = 28$

$diameter = 2 \times radius \\ diameter = 2 \times 28 \\ diameter = 56cm$

u'r done!!

Thnx✌️♥️~

Answer 2

Answer:

your answer = 56 cm

Step-by-step explanation:

circumference of a circle =2 π r

176=2×22/7×r

176=44/7×r

176×7/44=r

r=28

radius of a curcunferenc =28 cm

diameter of a circumference=28×2

=56 cm

i hope it may help you
