Answer:

Option C, $31.4\ cm$

Step-by-step explanation:

Step 1: Determine the formula

Formula → $C = 2*\pi *r$

Step 2: Determine the radius

$Radius = \frac{Diameter}{2}$

$Radius = \frac{10\ cm}{2}$

$Radius = 5\ cm$

Step 3: Determine the circumference

$C = 2 * \pi * (5\ cm)$

$C = 10\ cm * \pi$

$C = 31.4\ cm$

Answer: Option C, $31.4\ cm$

Angles of xyz are in the ratio 3:3:6. What are the measures of the angles

tankabanditka [31]

Let
x = 3a (first angle)
y = 3a (second angle)
z = 6a (third angle)

The total angle of a triangle is ALWAYS 180.
3a + 3a + 6a = 180
12a = 180
a = 15

Therefore, x = 45, y = 45, z = 90

Step-by-step explanation:

The numbers are 56 and 26. Let's prove it:

56/5 = 11 and a remainder of 1

56/6= 9 and a remainder of 2

26/5 = 5 and a remainder of 1

26/6 = 4 and a remainder of 2

56 + 26 = 82

The correct answer is B. 82
