Answer:
r=(A/π)^1/2
Step-by-step explanation:
A=πr^2. When dividing π on both sides, you get r^2 = A/π. Meaning that r = the square root of A/π, or (A/π)^1/2
X=3+√13, 3-√13
substitute y for 0 and solve for x
Answer:
15x*45 i think
Step-by-step explanation:
Answer:
500
Step-by-step explanation:
Subtract 4x from both sides
Then divide both sides by 9 to isolate y
Y=(6-4x)/9
