Question

A water and sprinkle our sins water out in a circular pattern how many feet away can it spread water if the area formed by the watering pattern is 379.94 square feet use 3.14

Answer 1

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 = $\pi r^{2}$

Area of a circle = 379.94 square feet  (given)

$\pi r^{2}$ = $379.94$

$3.14\times r^{2} = 379.94$

Dividing both side by 3.14

$r^{2} = \frac{379.94}{3.14} = 121$

Taking square root both side

$r = \sqrt[2]{11\times11}$        (Taking common)

$r = 11$

Therefore, radius = 11

Thus,  it can  spread water 11  feet away.
