Students were asked over to answer a question at education and to mention what is most important for them to succeed. The one which response stood out from the rest was practice. Successful people generally are not born successful; they become successful via hard work and persistence. This is how you can obtain your goals. the following are one of the answer and question example that you will be able to utilize to practice and boost your knowledge and also give you insights that may help you to preserve your study in school.

## Question:

The irrigation design for a new backyard is shown with four sprinkler heads and two walkways.

The distance between grid lines is 3 feet.

Which statements about the design are true? Check all that apply.

Each sprinkler head is placed more than 3 feet from the walkway.

If two additional sprinkler heads are placed on the lawn, every square foot of the yard would be watered.

The total area watered by each sprinkler is approximately 63.6 square feet.

The total area watered by all the sprinklers is approximately 254 square feet.

If the sprinklers were placed in two straight lines on the yard, they would water a greater amount of the lawn.

## Answer:

**Answer:**

Statements A, C, D are true

**Step-by-step explanation:**

A). As we can see distance from the sprinklers head to the walkway is more than one grid and length of one grid is 3 feet, so each sprinkler is placed more than 3 feet from the walkaway.

B). If two additional sprinkler heads are placed on the lawn, every square foot of the yard would be watered is not certain because the position of additional sprinklers is not defined.

C). Radius of the area watered by each sprinkler = 1.5 grid = 1.5×3 = 4.5 feet

So area watered by each sprinkler = π×r² = (3.14)(4.5)² = 63.58 ≈ 63.6 feet²

D). Area watered by one sprinkler = 63.6 feet²

therefore total area covered by four sprinklers = 4×63.6 = 254 feet²

E). If the sprinklers are placed in two straight lines on the yard then area watered by them will be same. No additional area will be watered by them.

From the answer and question examples above, hopefully, they can help the student take care of the question they had been looking for and take note of each and every thing stated in the answer above. Then can certainly have some sharing in a group discussion and also study with the classmate with regards to the topic, so another student also attain some enlightenment and still keeps up the school learning.
