Question

if circumference of a circle is 176cm. find it's radius​

Answer 1

Step-by-step explanation:

circumference is

$2\pi \: r \\ so \: \\ 2\pi \: r = 176 \\ finding \: r \\ r = 176 \div 2\pi \\ r = 28.011$

Answer 2

Answer :

• ☞ Radius of the circle is 28cm.

Solution :

✷ Given :

• Circumference of circle is 176cm.

✷ To Find :

• Radius of the circle.

━━━━━━━━━━

Circumference of the circle is given and we have to find its radius. we can easily find its radius using the formula :

$\red\bigstar\boxed{\text{ \sf Circumference of Circle} = 2\pi r }$

$\large\mathfrak{Substituting\: the \:values }$

$\leadsto 176 = 2 \pi r \\ \\ \leadsto 176 = 2 \times \dfrac{22}{7} \times r \\ \\ \implies r = \dfrac{7}{\cancel{22}}\times \dfrac{1}{2} \times ^8 \cancel{176} \\\\ \implies r = \dfrac{7\times ^4 \cancel{8}}{\cancel{2}} \\ \\ \implies r = 7 \times 4 \\ \\ \implies \underline{\boxed{\pink{\sf r = 28cm}}}$

Hence,

Radius of the circle is 28cm.
