The formule is about area of a circle.

We need to solve the equation for x. Where x is the radius of the circle.
In order to solve it for x, we need isolate it for x on left side.
So, first we need to get rid pi from left side.
On dividing both sides by pi, we get 


Taking square root on both sides, we get 


 
        
             
        
        
        
Answer:
410
Step-by-step explanation:
We can write the 10² as 100.
Therefore, the 4.1 x 10² would equal 4.1 x 100, 
To solve 4.1 x 100 we will move the point two positions to the right (since 100 has two zeros) 
When we move the point of 4.1 two positions to the right, we get 410.
Therefore, the numeral form of 4.1 x 10² = 410.
