Answer:
A) 781.3
Step-by-step explanation:
To find the volume of the cone, you must first find the radius and height of the cone. Which is 7km (radius) and 14km(height).
Next use the formula (Which is in the picture since it's too hard to type out on here)
I also would of explained it but I found it easier just to type it out (In the file attached below)
Finally the answer is 781.3 km

The equation for surface area of a sphere is SA=4*pi*r^2
We can plug in what we know to solve for r
400=4*pi*r^2
100=pi*r^2 (divide out the 4)
100/pi=r^2 (divide out the pi)
√(100/pi)=r (square root of both sides)
r=5.6 rounded to the nearest tenth
