Answer:

Depends on which place you're rounding to:

Step-by-step explanation:

Rounded to the tenths place (one number after the decimal point):

x = -6.6, -9.4

Rounded to the hundredths place (two numbers after the decimal place):

x = -6.59, -9.41

Rounded to the thousandths place (three numbers after the decimal place):

x = -6.586, -9.414

I don't think you'd need to round to the ten-thousandths place. If you do lemme know and I'll edit my answer. But you should know if the next digit is 5 or greater like in 15 you'd round up. If it's less than 5, you round down.

A circle has a diameter of 6 centimeters what is the approximate area of the circle

KiRa [710]

Answer:

28.26 $cm^{2}$

Step-by-step explanation:

The radius is half of the diameter. 6/2 = 3, so the radius of this circle is 3 cm.

The formula for the area of a circle is: π $r^{2}$

Plugging 3 into the radius, we have:

$3^{2}$ × π =

9 × π

We can round π to 3.14

9 × 3.14 = 28.26

Please help I’ll mark brainliest as long as you tell me how you got that answer, also I apologize if it’s kinda blurry. I hope y

Step-by-step explanation:

Not another one! ;)

A can be eliminated because the numbers don‘t match. B seems like a possible answer, let’s first check the others out. C and D can be slim instead because the variable, g, should be next to the 1.5 and 2.5. C and D both change the variable location. So, B.
