What is the circumference of a circle whose radius is 13?

Inessa05 [86]

Answer:

Circumference, C = 81.68 units

Step-by-step explanation:

Given that,

The radius of the circle, r = 13 units

We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :

$C=2\ \pi r$

$C=2\ \pi \times 13$

C = 81.68 units

So, the circumference of the circle is 81.68 units. Hence, this is the required solution.

When you are determining the probability of an event, why must the probability be between 0 and 1? Explain your answer.

Triangle angle sun theorem<br> what the value of y?<br> I will give brainlist

hichkok12 [17]

Answer:

y = 7°

Step-by-step explanation:

By interior angle sum theorem of a triangle.

$51 \degree + 87 \degree + 6y = 18 \degree \\ \\ \implies 138 \degree+ 6y = 18 0\degree \\ \\ \implies 6y = 180 \degree - 138 \degree \\ \implies 6y = 42 \degree \\ \\ \implies y = \frac{42 \degree}{6} \\ \\ \huge \red{\implies y =7 \degree} \\ \\$
