Answer:
1134.1 [cm²]
Step-by-step explanation:
A=πr2
Circle area = π * r² = π * 361 [cm²] ≈ 1134.1 [cm²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 19 [cm] * 2 = 38 [cm]
Answer: 2a-6=g
Step-by-step explanation:
2a-6=g
2 times the amount Adrianne sold minus 6 equals the amount Graham sold.
NOTE: I don’t know which option this is because you did not provide it, so please just select the one that contains my answer (or something similar with just different variables, both variables have to be different though).
Begin solving like you normally would. Add 2.25 to both sides and subtract 9x from both sides to try getting all x values on one side. However, you will find that after subtracting 9x from both sides, all x values go away, and you end with -2.25=1.6. This is not true (-2.25 is not 1.6), so the answer is no solution. There is no value of x which satisfies that equation.
