Question

find the radius of the circle if the circumference of the circle is equal to the perimeter of the square which is equal to 154 cm


thnx yug ​

Answer 1

According to question:-

✠ Given that:-

• Circumference of circle=Perimeter of square.

✠ To find:-

• Radius of the circle

✠ Formula used:-

$\large \underline{\boxed{\sf{ \red{\implies2\pi r = circumference_{circle}}}}}$

Where,

• π = 22/7 or 3.14
• r=radius

Solution:-

$\large\underline{\sf{ \implies2\pi r = 154 {cm}}}$

$\large\underline{\sf{ \implies2 \times \frac{22}{7} \times r = 154cm }}$

$\large\underline{\sf{ \implies \frac{44}{7} \times r = 154 {cm}}}$

$\large\underline{\sf{ \implies r = \frac{154 {cm} \times 7}{44} }}$

$\large\underline{ \boxed{\sf{ \red{\maltese\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: r = 24.5cm}}}}$
