ludmilkaskok [199]

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.

WILL ANSWER FIRST RIGHT ANSWER AS BRAINIEST

Ket [755]

Answer:

Step-by-step explanation:

Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as

1070=180(n-2) where n is the number of sides required here.

Making n the subject of the formula then following step by step

$n-2=\frac {1070}{180}$

$n=\frac {1070}{180}+2\\n=7.9444444444444\approx 8$

Therefore, the shape is octagon and it has 8 sides.
