Answer:
<h2>C ≈ 12.56 m, A ≈ 12.56 m²</h2>
Step-by-step explanation:
The formula of a perimeter (circumference) of a circle:

<em>d</em> - diameter
The formula of an area of a circle:

<em>r</em> - radius
We have <em>d = 2r = 4m → r = 2m.</em>
<em>Substitute:</em>
<em>Use π ≈ 3.14</em>


2,500 feet is the answer to your question. hope this helped
Answer:
The correct option is;
D. -8·t² + 18·t + 6 = 10
Step-by-step explanation:
The given equation of the height toy cannon launched on top of a platform is given as follows;
h(t) = -8·t² + 18·t + 6...(1)
Where "h" represents the height in meters, at time "t" seconds after the ball is launched
When the height is 10 meters, we can write as follows;
The height of the ball, h(t) = 10
Therefore, by substituting the value of h(t) in equation (1), h(t) = -8·t² + 18·t + 6, when h(t) = 10 we get;
-8·t² + 18·t + 6 = 10.
Answer:
C (i think i did it correctly)
Step-by-step explanation:
9 times 12 is 108 -> 108 - 60 = 1 hour and 48 minutes -> 48 plus 4 = 7:52am
