Answer:
12 feet
Step-by-step explanation:
It asks how many feet away from the sprinkler can water be spread. Therefore, in this scenario, we require the radius.
Area of a circle :
<u><em>Area (circle) = πr²</em></u>
<u><em /></u>
Solving :
⇒ 452.16 = 3.14 × r²
⇒ r² = 452.16 ÷ 3.14
⇒ r = √144
⇒ r = 12 feet
We need radius
Let that be r
- πr²=452.16
- 3.14r²=452.16
- r²=144
- r=√144
- r=12ft

Answer:
14
Step-by-step explanation:
divide 48 by 3 = 16
they must be consecutive even numbers
2 less than and two more than 16 are 14 and 18
14 + 16 + 18 = 48
the smallest is 14
