please help be a cool person and help u better know geometry?

Question

ok please help if u answer corectly u get best answer which means 10 pionts ok.on the math sheet it says to find the circumference of a circle is C = pi *d and i want to know what the d means and how u fint it.i know pi 3.14 please help correctly.

thanks people so much i finished my homework no need for help the second person gets best answer for answering correctly and explaining

Answer 1

D stand for diameter. (You'll also see equations with R - that's radius which is half of the diameter.) It's a straight line that crosses through the center of the circle.

Here's one of many, many web sites that might help you:

Answer 2

D is the diameter. It's the line that slices the circle in half. If it shows just the radius, multiply the radius by two to find the diameter. So let's say a circle's radius is 3. That means it's diameter is 6. To find the circumference, multiply 6 by 3.14. That means the circumference of the circle is equal to 18.84
Hope that helps!

Answer 3

Pi is technically 3.14159265358979323846....

And "d" stands for diameter, equal to r^2

You should pay better attention in math class.

Answer 4

c equals circumfrance
d equals 2r
2r equals d
r equals radius
hey, is this a test? better not be
