Answer:

Hey!

<h2>The area would be 13.85</h2><h2 />

Step-by-step explanation:-

Area of a circle's equation is π $r^{2}$ (pi $r^{2}$ )

Since the radius is 2.1 and value of pi is 3.14cm,

area is

$2.1^{2}$ x 3.14

4.41 x 3.14

= 13.85

25 is what percent less than 35

mars1129 [50]

Difference between 25 and 35 = 35 -25
   = 10
Then
percentage by which 25 is less than 35 =(10/35) * 100
   = (2/7) * 100
   = 200/7
   = 28.57 percent
So 25 is 28.57% less than 35.This is the only clear way of solving these kind of problems. I hope you have understood the method used to solve this problem. Hopefully you can do such type of problems without needing any help.
