Answer:

arc = 5π units

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here we have a semicircle with d = 10, so r = 5, then

arc = $\frac{1}{2}$ × 2π × 5 = 5π units

Ghella [55]

Answer:

The number of ways are 40320.

Step-by-step explanation:

Consider the provided information.

Ms. Smith keeps eight different cookbooks on a shelf in one of her kitchen cabinets.

We need to determine the number of different ways to put eight cookbooks on the shelf.

We need to select 8 cookbooks taking 8 at a time.

So use the permutation formula: $^{n}P_{n}$

Substitute n=8 and simplify.

$^8P_8=\frac{8!}{(8-8)!}\\8!=40320$

Hence, the number of ways are 40320.
