A) The formula for the volume of a sphere in terms of its radius (half the diameter) is

For your 18 cm sphere, the volume is

B) If the diameter were reduced by half, the volume would be

of the original volume.
Isnt it less ? Correct me if im wrong
I don’t see an image for this.
Answer is C hope this helps
Answer:
When a line is parallel to another line, they have the same slope. So far the equation would be, y=4x+b. To find the value of b, substitute the given point into the equation.
8=4(-1)+b
8=-4+b
b=12
So, the equation of the line is y=4x+12.
