Formula for the area of a circle: A = pi x r^2
We are given the diameter in this problem, but we need the radius. To find the radius, we will need to divide the diameter by 2.
8 / 2 = 4
A = pi x 4^2
A = pi x 16
A = 16pi cm^2
Hope this helps!! :)
Answer: Determine the difference in y- coordinates of these two points
Step-by-step explanation:
Answer:
y=5/2x+2
Step-by-step explanation:
rearrage equation: y=5/2x-7
new slope is same: y=5/2x+b
substitue point (-2,-3):
-3=5/2(-2)+b
-3=-5+b
-3+5=b
2=b
