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.

Which of the following cannot be solved using the quadratic formula?

VLD [36.1K]

Answer:

Step-by-step explanation:

Quadratic formula is used only to solve the quadratic equations .

Means the equation of the form

$ax^{2} +bx+c=0$

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
