<h2>Answer:</h2>

The solid which is generated when the semicircle is rotated about the line is:

Sphere.

<h2>Step-by-step explanation:</h2>

We know that when a semicircle is rotated about any line then the three dimensional figure or a solid that is formed on this rotation transformation is Sphere.

Hence, the correct option is:

Sphere.

( Also, a cylinder is obtained when a right triangle is rotated about a given line.

and a cylinder is obtained when a rectangle is rotated about a given line )

4. Find the value of n that makes this equation true. (Use

andreyandreev [35.5K]

Answer:

$n=4$

Step-by-step explanation:

We start off with 3.2n + 13.3 = 26.1.

We need to get n by itself.

Subtract 13.3 from both sides.

$3.2n+13.3-13.3=26.1-13.3$

$26.1-13.3=12.8$

We end up with: $3.2n=12.8$

Divide 3.2 on both sides to get n by itself.

$\frac{3.2n}{3.2} =\frac{12.8}{3.2}\\ n=4$
