Answer 2

The radius is 42 cm.

Step-by-step explanation:

Given : The circumference of a circle exceeds its diameter by 180 cm.

To Find : It’s radius ?

Solution :

The circumference of circle is $C=2\pi r$

The diameter of the circle is $d=2r$

The circumference of a circle exceeds its diameter by 180 cm.

i.e. $C-d=180$

$2\pi r-2r=180$

$2r(\pi-1)=180$

$r=\frac{180}{2(3.14-1)}$

$r=\frac{90}{2.14}$

$r=42.056$

Therefore, approximately the radius is 42 cm.
