The formula for area of a circle is π × radius^2, and to find the radius we can just divided the diameter by 2 and get 2 inches. You don't need to use a calculator here, because π is approximately equal to 3.14, so 3.14 × 2^2 = 12.56, which is answer B. I hope this helps!
Answer:
Step-by-step explanation:3,9,27,81 because this is multiplication
Answer: y = -4x-9
Step-by-step explanation:
parallel slope means it's the same slope as the given equation
y+1=-4(x+2)
y+1 = -4x-8
y = -4x-9

Answer:
The slope is -3/4
Step-by-step explanation:
We need two points to find the slope
We have one point at (0,5) and we have one point at (4,2)
We can use the slope formula
m = (y2-y2)/(x2-x1)
= (2-5)/( 4-0)
= -3/4
The slope is -3/4
