Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r.
I got 314 cm^2 is the surface area, but it always helps to double check work! Hope this helps!

If the "problem of 3 and a number " is multiplying:
If it's about adding:
Scenario A: If it's 3 and z, then that means it's 3, and we're adding 4, so it's
(make sure to put () around the 3
!)
Scenario B: If 3 and z is also 3+, then the equation is
(also use () on this too!)
Answer:
A. y = 7(x + 1)²-3
Step-by-step explanation:
Parabola:
Putting into vertex form, remember that:
In this question:
, to put into this format:
We add one inside the parenthesis to do this. The parenthesis is multiplied by 7, so for the equivalent, we also have to subtract 7. Then
Vertex form:
So the correct answer is:
A. y = 7(x + 1)²-3
