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:
y = 2x-5
y=-x+4
Step-by-step explanation:
Just need to solve the:
x+y=4
y-2x=-5
And we have:
x=3
y=1
Then replace x and y into the answer to find the correct one
