Question

The ratio of radius and side of a circle and square are7:5. If circumference of circle is 44cm find the perimeter of square.

Answer 1

Answer:

If 7:5 is the ratio of the radius of a circle to the side of a square, and if 44 cm is the circumference of the circle, then the perimeter of the square is 20cm

Step-by-step explanation:

Given

The ratio of the radius of the circle to the side of the square is 7:5

That is we take 7x as the radius of the circle, then 5x will be the side of the square

Given

Circumference of the circle = 44cm

That is

$2*\frac{22}{7} *7x = 44\\\\44x = 44\\\\x = \frac{44}{44} \\\\x = 1$

So, the perimeter of the square is 4* side of the square

= 4* 5x = 4* (5*1) = 4*5 = 20cm

So the perimeter of the given square is 20 cm
