Answer 1

Step-by-step explanation:

So, R will be 63 m (or cm...according to what has been given in the question)

Answer 2

Answer :-

• The radius of the circle is 63 units.

To find :-

• The radius of the circle.

Step-by-step explanation :-

• Here, the circumference and the value of pi are given to us. We have to find the radius of the circle.

We know that :-

$\bigstar \:\underline{\boxed{\sf{Circumference \: of\: a\:circle = 2\pi r}}}$

Where,

• r = Radius.

Here,

• Circumference of the circle = 396 sq. units.

• π = 22/7.

Let :-

• The radius of the circle be "r" units.

Substituting the given values in this formula,

$\bf{\longrightarrow 2 \pi r = 396}$

$\bf{\longrightarrow 2 \times \dfrac{22}{7} \times \: r = 396}$

$\bf{\longrightarrow \dfrac{44}{7} \times \: r = 396}$

$\bf{\longrightarrow 44 \times r = 396 \times 7}$

$\bf{\longrightarrow 44 \times r = 2772}$

$\bf{\longrightarrow r = \dfrac{2772}{44}}$

$\bf{\longrightarrow r = \cancel{\dfrac{2772}{44}}}$

$\bf{\longrightarrow r = 63}$

Hence :-

• The radius of the circle is 63 units.
