Answer:
11  feet away.
Step-by-step explanation:
Given:
A water and sprinkle our sins water out in a circular pattern
 Area formed by the watering pattern is 379.94 square feet 
To find:
How many feet away can it spread water means we have to find distance from the middle point to the last end of circular pattern of water sprinkling (radius of a circle) = ?
solution:
By using ,Area of a circle = 
Area of a circle = 379.94 square feet  (given)
 =
 = 

Dividing both side by 3.14

Taking square root both side
![r = \sqrt[2]{11\times11}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B2%5D%7B11%5Ctimes11%7D) (Taking common)
        (Taking common)

Therefore, radius = 11
Thus,  it can  spread water 11  feet away.

Answer:
r  = 6
Step-by-step explanation:
To get the value of r we will use the pythagoras theorem a shown;
PR² = QR² + PQ²
(4+r)² = 8² + r²
Expand
16+8r+r² = 64 + r²
16 + 8r = 64
8r = 64 - 16
8r = 48
r = 48/8
r = 6
Hence the value of r is 6
 
        
             
        
        
        
8 ÷ 544 = 0.0147058824, 544 ÷ 8 = 68
