Answer: The surface area of the ball is 15.90 in².
Step-by-step explanation:
1. The ball is spherical, therefore to calculate its surface area, you must apply the formula for calculate the surface area of a sphere, which is:

2. You can calculate the radius (
) with the diameter given in the problem, as following:

3. Substitute this value into the formula. Then, you obtain that the result is:

Answer:
The third option. (the one where it intersects on the y line)
Step-by-step explanation:
If you solve for the system of equations, you will find that it is (0,3), so it intersects on the y line. Additionally, it is on the top because it is positive.
Answer:
try 3x=30 or 10
Step-by-step explanation:
Answer:
c+1/12
Step-by-step explanation:
18/24c-7/12+7/24c+8/12-4/24c=c+1/12
I'm pretty sure the answer is G. I'm not 100% sure tho. Hope this helps! :)
