Answer:
The answer is (b) 18
Step-by-step explanation:
16 = 4
18 = 4.24264068712
25 = 5
36 = 6
r = 22 ft the sprinkler sends water until 22 feet away
A circular pattern has an area of 1,519,76 ft²
And the areaof a circle is:
A(c) = π*r²
A(c) = 3,14 * r² ⇒ 1,519,76 = 3,14 * r²
r² = 1,519,76/3,14 ⇒ r² = 484
r = √484
r = 22 ft
