Aspheres radius is multiplied by 2. how is it’s surface area affected

The surface area is multiplied by 3.

Step-by-step explanation:

If r is the radius of a sphere its surface area = 4(pi)r^2. If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2. So the surface area becomes 4-fold or the increase in surface area is 300%.

the first one, all those points on the line just make a strait line.

1/800 is the right answer
