Formula for diameter?
d=2r diameter=2 times the radius
What is the formula for finding the diameter of a circle?
two times the radius (d=2r)
0.3 times 2r- 0.3 times3 equals 0.2r plus 0.9?
0.3(2r) - 0.3(3) = 0.2(r) + 0.9Clear parentheses:0.6r - 0.9 = 0.2r + 0.9Multiply each side by 10:6r - 9 = 2r + 9Add 9 to each side:6r = 2r + 18Subtract 2r from each side:4r = 18Divide each side by 4:r = 18/4 = 4.5
What is 12-2R?
12-2r = 10
What is 7-2r equals 13?
If: 7 -2r = 13 Then: r = -3

What is 5r plus 7 equals 13 plus 2r plus 3r?
1)5r+7=13+2r+3r 2)5r+7=13+5r 3)5r's cancel 7=13 4)Subtract thirteen on both sides 7 =13 -13 -13 5)Answer is no solution because -6 doesn't equal to 0. -6=0 NO SOLUTION!!! Have fun with math!
How do you do absolute 2r plus 9 absolute equals 5?
|2r + 9| = 5 So 2r + 9 = 5 or 2r + 9 = -5 so that 2r = -4 or 2r = -14 r = -2 or r = -7
0.3 times 2r- 0.3 times3 equals 0.2r plus 0.9?
0.3(2r) - 0.3(3) = 0.2(r) + 0.9Clear parentheses:0.6r - 0.9 = 0.2r + 0.9Multiply each side by 10:6r - 9 = 2r + 9Add 9 to each side:6r = 2r + 18Subtract 2r from each side:4r = 18Divide each side by 4:r = 18/4 = 4.5
What is 12-2R?
12-2r = 10
How do you find circumference?
The formula is 2 times radius times pi or the diameter times pi. Circumference is 2r times pi. Assuming you are referring to a circle.
What is 4r2-25 factored?
4r2-25 = (2r)2-52 = (2r-5)(2r+5)
How do you solve 2r-1 equals 9?
2r-1=9 2r =10 r =5
