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 w
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.

natima [27]

Answer:

125

Step-by-step explanation:

6 and 7 are on a straight line (180 degrees)

Angle 2 is equal to Angle 6

Therefore 180 - Angle 6 = Angle 7

180 - 55 = 125

A = {1, 2, 5, 7}<br> B = {3, 4, 6, 7}<br> C = {0, 5, 8, 9}<br> Find A U B U C.
castortr0y [4]

Answer:  In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other.

A U B U C = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Step-by-step explanation:

A = {1, 2, 5, 7}

B = {3, 4, 6, 7}

C = {0, 5, 8, 9}

A U B U C = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }
