Answer:

So, for an equilateral triangle we have 360/3 = 120 degrees as the exterior angle, and 180-120 = 60 degrees as the interior angle. For a square, you get 360/4 = 90 degrees as the exterior angle and 180-90 = 90 degrees as the interior angle.

Use the circle to answer the questions

insens350 [35]

Answer:

Diameter: 10.8 cm

Circumference (in terms of π): 10.8π cm

Circumference (approximate): 33.91 cm

Step-by-step explanation:

Hi there!

We're given:

The radius (5.4 cm)

1) Determine the diameter

$d=2r$

Multiply the radius 5.4 cm by 2

5.4 × 2 = 10.8

Therefore, the diameter of the circle is 10.8 cm.

2) Determine the circumference of the circle

$C=\pi d$

Plug in the diameter 10.8

$C=10.8\pi$

Therefore, the circumference of the circle in terms of π is 10.8π cm.

3) Determine the approximate circumference of the circle

$C=10.8\pi\\C=10.8(3.14)\\C=33.91$

Therefore, the approximate circumference of the circle is 33.91 cm.

I hope this helps!

-9b-6=-3b +48 Step by step

Travka [436]

Answer:

b = -9

Step-by-step explanation:

1. Move the variables to the left side. Be sure to change the terms (add/subtract)

-9b-6 = -3b+48

-9b+3b-6 = 48

2. Combine like terms.

-9b+3b-6 = 48

-6b = 48 + 6

3. Divide both sides by -6.

-6b = 54

b = -9
