Question

find the cirumference red area of the circle of radius 15 CM ​

Answer 1

Given :

• Radius = 15 cm

To Find :

• Circumference of The Circle

Using Formula:

• Circumference of The Circle = πr²
• Where,
• π = $\sf \frac{22}{7}$

• r = Radius = 15 cm

Explanation Of The Answer:

$\sf \implies Circumference \: \: of \: \: The \: \: Circle = πr²$

$\sf \implies Circumference \: \: of \: \: The \: \: Circle = \frac{22}{7} × (15)²$

$\sf \implies Circumference \: \: of \: \: The \: \: Circle = \frac{22}{7} × 225$

$\implies \boxed{ \sf Circumference \: \: of \: \: The \: \: Circle = \frac{4950}{7} \: \: cm²}$

$\implies \boxed{\sf Circumference \: \: of \: \: The \: \: Circle = 707.1428 \: \: cm²}$
