Answer:
A graphing calculator is more accurate than graphing by hand. If the slope and/or y-intercept is a fraction or decimal, it is more difficult to accurately graph by hand.
Step-by-step explanation:
The formula for the area of a circle is A=πr².
A=πr²
A=π4²
A=π16
Assuming you use 3.14 for π,
A≈50.27
Answer:
71
Step-by-step explanation:
x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 456
6x + 30 = 456
add -30 to each side
6x = 426
divide each side by 6
x = 71
Yea it's good but make sure to check your answers to see if you did anything wrong.
