Suppose the circumference of a circle is 15pi. What is its diameter?

1 answer:

7 0

The circumference of a circle is proportional to its diameter.

$C\propto d\\ \\ \therefore \quad C=kd$

Now, when d=1, C=π, therefore:

k=π

This means that:

$C=\pi d$

If C=15π:

15π=πd

Therefore:

d=15

Find each missing angle measure<br> 3=<br> 4=

Yanka [14]

Answer:

<4 = 88

<3 = 92

Step-by-step explanation:

The sum of the angles of a triangle is 180

<4 + 45+ 47 = 180

<4 + 92 = 180

< 4 = 180-92

<4 = 88

We know the <3 and <4 form a line

<3 + <4 = 180

<3 + 88 = 180

< 3 = 180-88

<3 = 92

Answer:

<h2> no, because the remainder is 126</h2>

Step-by-step explanation:

if x+3 is a factor, then -3 is a root of expression, and the remainder would be 0

calculating remainder:

$-3(-3)^3+6(-3)^2+6(-3)+9=-3\cdot(-27)+6\cdot9-18+9=\\\\=81+54-9=126$
