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!! :)
Simplify:

Answer:
there are millions of video games, ranging from all different prices, so it all depends on what game.
Step-by-step explanation:
Slope-intercept form: y=mx+b, with m being the slope and b being the y-intercept. First, plug in the given slope into the slope form:
y=2x+b
Now, given the coordinates (1,4), you can plug the coordinates into the equation for x and y respectively, to solve for b (the y-intercept).
4=2(1)+b
4=2+b
Subtract 2 from both sides.
2=b
The y-intercept is 2.
Now, plug that into the equation:
y=2x+2
The answer is y=2x+2.
I hope this helps :)
