Question

What is the radius of the circle if its circumference is 75/2 cm

Answer 1

Let see your answer !!!!!

We have

Circumference of a circle = 75/2 cm

Radius = ?

Solution

Circumference of a circle = 2πr

$= > \frac{75}{2} = 2 \times \frac{22}{7} \times r \\ \\ = > \frac{75}{2} = \frac{44}{7} \times r \\ \\ = > r = \frac{75}{2} \times \frac{7}{44} \\ \\ = > r = \frac{525}{88} cm$



Thanks :))))

Answer 2

Heya !!







Let radius of the circle be R cm.




Circumference of circle = 75/2




2πR = 75/2





2 × 22/7 × R = 75/2





R = ( 75 × 7 ) / ( 2 × 2 × 22 )




R = 525/88 cm.



Hence,



Radius of circle ( R ) = 525/88 cm.
