For this case, we have that by definition, the circumference of a circle is given by:

$C = \pi * d$

Where:

d: Is the diameter of the circle given by 2r, that is, twice the radius.

If we have a circle with a diameter equal to 8cm, then the circumference is given by:

$C = \pi * 8 \ cm$

ANswer:

Option C

$8 \pi \ cm$

Answer:

The correct answer is option 3). 8π cm

Step-by-step explanation:

Formula for circumference of circle

circumference = 2πr where r is the radius of circle.

It is given that, Circle with center D and diameter of 8 cm labeled.

To find the circumference

diameter = 8cm

radius = diameter/2 = 8/2 = 4

circumference = 2πr

circumference = 2 * π * 4 = 8π

Therefore the circumference of given circle is

The correct answer is option 3). 8π

Answer:

Step-by-step explanation:

The word elevation means above or on top.

This means our answer must be a positive so option C is eliminated.

Sea level is 0 ft

So we can make an equation with x as our unknown:

x = sea level + feet elevated

x= 0 + 373

x =373

Therefore Option D is the correct answer

Find and label -0 on the number line. Explain. Does -0 just mean 0?

poizon [28]

The opposite of the number 0 that is -0 on the number line will be equal to 0 itself.

A number line may be defined as a scale consisting of numbers labelled from 0 to 9 which are used to plot or mark different points for various entities. Number line extends from 0 to 9 in the positive side that is usually taken as right-hand side and it extends from 0 to -9 in the negative side that is usually taken as the left-hand side. The numbers on the right-hand side of number line have their opposites on the left-hand side. The opposite of a number x is taken as -x. For example, the opposite of 4 is taken as -4 and 4 lies on right-hand side whereas -4 lies on left-hand side. 0 lies on the center of number line and is taken as the main point. It is neither positive nor negative so the opposite of 0 is 0. The figure of number line is attached.
