Suppose the diameter of a circle is 6 units What is its circumference?

Kipish [7]

Answer:

18.84 estimated, 6π exactly

Step-by-step explanation:

Hi!

The formula for finding the circumference of a circle is 2πr:

In that case, all we need to do first is to divide the diameter by 2, so we can substitute that into the equation.

6 ÷ 2 = 3

So we have 2π × 3 to solve.

2π × 3 = 6π

We can estimate the circumference by multiplying by 3.14.

6 × 3.14 = 18.84

(actually multiplying by π gives 18.849... which is pretty close!)

Thus, the circumference is $\boxed{6\pi{\text{\:or\:18.84\:roughly}}}$ .

Hope this helps!

Express as a trinomial (3x+8) (x+10)

docker41 [41]

Answer:

$3x^{2} +38x+80$

Step-by-step explanation:

Hello!

A trinomial is a expression consisting of three different terms

To turn this into a trinomial we multiply everything to each other

3x

3x * x = $3x^{2}$

3x * 10 = 30x

8

8 * x = 8x

8 * 10 = 80

Now we put them all together in an equation

$3x^{2} +30x+8x+80$

Combine like terms

$3x^{2} +38x+80$

The answer is $3x^{2} +38x+80$

Hope this helps!
