A) From the function p(t)=6(t), we know that p is 6t, so we plug this into it, to get 3.14 * (6t)^2, or 113.04t^2.
B) Using what we got from A), we plug it in and get 113.04 * 8 * 8, or 7234.56 (Use a calculator on this, or just bash it with pencil and paper).
Answer:
1675 ft
Step-by-step explanation:
For us to calculate how close the windmill is to the fire, if we imagine it as a triangle, the distance from watch tower to the fire will be:
tan θ= opposite/adjacent
opposite=140 ft
adjacent = x
θ=3°
Thus;
tan 3 = 140/x
x=140/tan 3
x = 2,671.359 ft
Now, the distance from watch tower to windmill will be:
tan θ=opposite/ adjacent
θ=8°
opposite=140 ft
adjacent=y
thus
tan 8 = 140/y
y = 140/tan8
y=996.15 ft
Now, the distance between fire and wind mill will be:
x - y = 2671.359 - 996.15
x - y = 1675.209 ≈ 1675 ft
The answer would be 8900
Reason: when you round to 2 significant figures you are trying to reduce the number to 2 digits and the rest will become 0 to indicate a place value
