The spray from a sprinkler creates a circle with a radius of 15 feet. Which of the following is the best approximation of how many square feet of grass the sprinkler covers?
47
94
225
707

Option 4 - 707

Step-by-step explanation:

Step 1:

Given that the spray from a sprinkler creates a circle with a radius of 15 feet.

We need to determine  how many square feet of grass the sprinkler covers. To find this we need to find the circle's area that the sprinkler covers.

Hence we need to determine the circle's area  having radius 15 feet

Step 2 :

We have the area of  circle having radius r as pi * r ^2

So when r = 15, the area is

(22/7) * 15* 15 (where pi = 22/7)

= 707.14

Hence the area which is covered with  the spray from the sprinkler is approximately 707 feet.

Option 4 is the answer

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
