1.What is the radius of a circle, which Touches All sides of a square, If the perimeter of square is 60cm?

Answer 1

Hi,
=====================================

To find, each side of the square, we have to divide the perimeter of the square by 4...          [Because, square has 4 sides]

So,
$\frac{60}{4}$=15cm each side of the square

sO, THE DIAMETER=15CM

Radius= $\frac{diameter}{2}$

So, r=$\frac{15}{2}$ = 7.5cm answer
===============
Hope you are helped :-)

Answer 2

HEY!!

Perimeter of the square = 60cm
If square has four sides then,

60÷4 = 15

So each side of a square will be 15cm

If each side of a square is 15cm then diameter of the circle will also be 15cm

Perimeter of square = 60cm
Each side of a square= 15cm
Diameter of circle= 15cm

Radius= Diameter÷ 2
= 15cm ÷ 2
= 7.5cm

Ans)) Radius of the circle is 7.5cm
