The diameter of a circle is 8 cm. Find the circumference \textit{to the nearest tenth}to the nearest tenth.

25.1 units

Step-by-step explanation:

The formula for the circumference of a circle is:

OR

Since we have the diameter, I'm just going to use that. You can also use 4 as the radius, since half of the diameter is the radius.

Rounded to the nearest tenth:

= 25.1 units

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
