Answer:
Volume = 35185.8 
Step-by-step explanation:
Recall the formula for the volume of a cone: 
Where R is the radius of the cone's circular base (in your case half of 80 km,(that is 40 km)
And h stands for the height of the cone (in your case 21 km)
We replace such in the formula and calculate its final value:
We round it to the number of decimals your problem request (let's say to one decimal) and also include the cubic units:
Volume = 35185.8
Answer:
85° = ∠x {corresponding angles}
∠x = ∠1 {vertically opp. angles}
And, ∠2 + 103° = 180° ( co-interior angles)
∠2 = 180° - 103°
∠2 = 77°
Now, m∠1 + m∠2 = 85° + 77°
= 162°
Hemce, option A. is the right answer.
The answer is x^3-10x^2-8x+192
The answer would be 60 miles per hour
Answer:
The answer to your question is: 54°F
Step-by-step explanation:
Data
Ti = 78°F
Initial hour = 2:00
Temperature drops 4°F every hour
Temperature at 8:00 = ?
Process
2:00
3:00 78-4 = 74°F
4:00 74-4 = 70°F
5:00 70-4 = 66°F
6:00 66-4 = 62°F
7:00 62-4 = 58°F
8:00 58-4 = 54°F
