Please help me in number 20 please I need it ASAP
Ad libitum [116K]

Answer:

r=\sqrt{\frac{A}{\pi}}

Step-by-step explanation:

Given:

The area 'A' of a circle with radius equal to 'r' is given as:

A=\pi r^2

In order to rewrite the given formula in terms of radius 'r', we need to isolate 'r'.

Dividing both sides by π, we get:

\frac{A}{\pi}=\frac{\pi r^2}{\pi}

As \frac{\pi}{\pi}=1, the above equation becomes:

r^2=\frac{A}{\pi}

Taking square root both the sides, we get:

\sqrt{r^2}=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{A}{\pi}}

We neglect the negative result while taking square root as the radius can't be a negative number.

Thus, the formula for radius 'r' in terms of area 'A' is given as:

r=\sqrt{\frac{A}{\pi}}

Solve the proportion<br> 44/p = 11/5
Sholpan [36]
44   =   11 
----       ----
 p           5    
 
 Cross multiply 

44*5 = 11p 

 You end up with ; 
220    =  11p  

Divide 220 by 11 to get p by itself 

20 = p  <-- that's your answer 
 
hope i helped :)
