Answer:

Diameter: 10.8 cm

Circumference (in terms of π): 10.8π cm

Circumference (approximate): 33.91 cm

Step-by-step explanation:

Hi there!

<u>We're given:</u>

  • The radius (5.4 cm)

<u>1) Determine the diameter</u>

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.

<u>2) Determine the circumference of the circle</u>

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.

<u />

<u>3) Determine the approximate circumference of the circle </u>

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!

Answer:

The temperature at midnight is -12 degree Celsius

From midnight to 6:00 am, the temperature rose by 8 degree Celsius

X - (-20) = 8

X = 8-20

X = -12 degree Celsius.

The temperature at midnight is -12 degree Celsius.
