Answer:

x = 200

Step-by-step explanation:

$\frac{1x}{5}$ - $\frac{2(15)}{3}$ = 30

$\frac{x}{5}$ - 10 = 30

$\frac{x}{5}$ = 40

x = 200

<h2><u>Answer</u> :</h2>

The Answer is 2nd one

69.08 cm

<h2><u>Explanation</u> :</h2>

<h3>Given :</h3>

Radius of a circle = 11 cm

Circumference of the circle = ?

<h3>Solution :</h3>

As, we have radius of the circle is 11 cm and to find circumferemce, we have a formula :

$\large \underline{\boxed{\bf{Circumference = 2\pi r}}}$

By filling value of r = 11 cm and π = 3.14, we have :

$\sf : \implies Circumference = 2 \times 3.14 \times 11 \: cm$

$\sf : \implies Circumference = 2 \times \dfrac{314}{100} \times 11 \: cm$

$\sf : \implies Circumference = \dfrac{628}{100} \times 11 \: cm$

$\sf : \implies Circumference = \dfrac{6908}{100} \: cm$

$\sf : \implies Circumference = 69.08\: cm$

Hence, circumference of the circle is 69.08 cm.
