I assume that you want to know the temperature at a certain timing.
Well, you know that at 12:00 pm, the temperature was 12 F and that it decreases by a steady rate of 2 F each hour.
This means that at 1:00 pm, the temperature was 12-2 = 10 F
At 2:00 pm, the temperature was 10-2 = 8 F
At 3:00 pm, it was 8-2 = 6 F
.......and so on
You can follow this sequence to the timing you are looking for.
The formula for area of a cone is A=πr(r+√h²+r²). The radius is half the diameter, so 22.5.
Plug our numbers into the formula.
A=π22.5(22.5+√96²+22.5²)
the answer is 8560.16
Midpoint formula
mid of (x1,y1) and (x2,y2) is

so
(22,15)=

therefor
22=

and
15=

slv each
22=

times both sides by 2
44=18+x1
minus 18 both sides
26=x1
15=

times both sides by 2
30=6+y1
minus 6
24=y1
the other point is (26,24)
Answer:
We know the diameter is 3 inches. We need the radius to find the area. By dividing the dimater by 2, we get the radius of 1.5 inches. The answer is 7 inches squared.
Brainliest would be great.
