can you help me
i really need help in math
I need to see the picture so I can answer
To find the volume of a sphere, you will use the formula for finding volume of a sphere. You will use the diameter to find the radius. r = d/2, so the radius is 5 in
V = 4/3 x pi x r^3
4/3 x 3.14 x 5^3
V = 523.6 cubic inches
The volume of this sphere is approximately 523.6 cubic inches.
The answer to this equation would be x=4. Is that what u were asking?
Answer:
C
Step-by-step explanation:
Quadratic formula is used only to solve the quadratic equations .
Means the equation of the form

In this the x^2 part is must because that only makes the equation a quadratic.
Looking at the four options given to you , only the option C has the missing x^2 term, which makes it a linear equation and hence the quadratic formula cannot be applied there .
So the right option for your question with the quadratic formula is
option
C
