**Step-by-step explanation:**

C=2πR=πD=3.14*32=100.5 mm

**Answer:**

1/5

**Step-by-step explanation:**

The length of AC is found using the Pythagorean theorem which is a^2+b^2=c^2.

In this case your equation would look like 4^2+4^2=c^2.

Four to the power of two is 16 so 16+16=c^2.

16+16=32

32=c^2

Root 32 = c

Length AC is root 32.

The answer is A.

Divide 300 by the number of faces of a cube.

Since there are 6 faces on a cube then we divide it.

300 ÷ 6 = 50.

So exactly 50 times.

Hope this helps :)

**Answer:**

<u>**The correct answer is D. 12√2, 12√2, 24.**</u>

**Step-by-step explanation:**

Let's recall that a property of the right triangles 45 - 45 - 90 is that the lengths of the sides of this type of triangles are in the ratio 1 : 1: √2.

Thus, if the hypotenuse is 24 units, the length of the legs is 12√2. We calculated it this way:

24/√2 = x/1

x√2 = 24

x = 24/√2

x = (24 * √2) / (√2 * √2) (For not having a square root in the denominator)

x = 24√2/2

x = 12√2 (Most simplified expression)

<u>**The correct answer is D. 12√2, 12√2, 24.**</u>
