Surface area o fthe ball = 4 * 3.14 * radius^2
if diameter = 1.680 then radius = 1/2 * 1.680 = 0.84
so surface area = 4 * 3.14 * 0.84^2 = 8.862

Answer:
y = 5.4x + 23.5
Step-by-step explanation:
Since the service charges $23.50 for every hour, you have to multiply x by 23.5 like this: 23.5
There is a flat fee of $23.50, so you have to add 23.5 on top of that like this: 5.4x + 23.5
All of this has to add up to y; 5.4x + 23.5 = y
The answer is 5 you can also use your fingers no I’m not calling you dumb I’m just saying you can
