What is C equals 2r for r?
If: C = 2r Then: r = C/2
How do you solve 2r-1 equals 9?
2r-1=9 2r =10 r =5
What is 32 plus 3r equals 82-2r?
A math problem
What is the circumference of a circle with a 14 foot radius?
You can use the following formula: C=2r∙3.14 Therefore C=2∙14∙3.14 Find the product of 2 and 14 which equals 28. Now C=28∙3.14 Find the product of 28 and 3.14 which equals 87.92. Therefore the circumference is 87.92ft.
R plus s equals 4 2r plus 3s equals 8?
r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.
