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:
The second one I believe
3=%20
4=%14.17
5=%48.8
6=%165
7=%75
8=%15

Your Answer is C
x=5
y=12
the equation is
12x-5+125=180
12x+120=180
12x=60
According to the question
8y+29=125
8y=96
