The perimeter of a circle is 88 mtr. Find the radius :​

Answer 1

Answer:

The radius of a circle is $14$ m.

Step-by-step explanation:

Concept:-

• The perimeter of a circle is the length of the circular arc. Thus, the perimeter of a circle is called the circumference of a circle.
• Circumference of a circle = $2\pi r$

Step 1 of 1

Given:-

The perimeter of a circle is $88$ m.

To find:-

The radius of a circle.

Let the radius of a circle be $r$.

Since the perimeter of a circle is 88m, i.e.,

The circumference of a circle = 88 m

⇒ $2\pi r$ = 88

Now, find the value $r$.

$r$ = 88/$2\pi$

$r=\frac{88}{2\times\frac{22}{7} }$

$r=\frac{88\times7}{2\times22}$

$r$ = 2 × 7

$r$ = 14 m

Therefore, the radius of a circle is 14 m.
