Volume of a sphere can be found by using the formula V=\frac{4}{3}  \pi r^{3} where r is the radius of sphere.

Lianne drew a sphere with a radius of 7 in that is r= 7 in .she has written \frac{\pi}{3} and need to find what should be multiplied in numerator with pi.

V=\frac{4}{3}  \pi  r^{3}   =\frac{4\pi r^{3} }{3}   =\frac{\pi}{3}   (4 r^{3}  )

As r= 7 she needs to multiply numerator 4 r^{3}  = 4 (7^{3)}  =4(343) =1372

The number to be multiplied is 1372.

Suppose that a classmate asked you why (2x + 112 is not (4x² + 1). What is your response to this classmate?
aleksandr82 [10.1K]

The given expression is the square of a binomial, such that:

(2x + 1)^2 = 4x^2 + 4x + 1

Then the correct option is C.

<h3>Are the expressions equivalent?</h3>

We want to see if:

(2x + 1)^2

Is equivalent to (4x^2 + 1).

First, this is false, let's prove that.

We have the square of a binomial (2x + 1)^2. Remember the general formula:

(a + b)^2 = a^2 + 2ab + b^2

So if we apply this to our expression we get:

(2x + 1)^2 = (2x)^2 + 2*2x*1 + 1^2 = 4x^2 + 4x + 1

Then, the correct option is C.
