Answer:
Subtract the two diameters and multiply by 0.5
Step-by-step explanation:
Calculating the Radius of the hole gives distance to the inner edges WHILE the Radius of the coin gives us the distance to the outer edges.
By subtracting the output we can then get the difference between both distances.
If hole diameter = 5mm and coin diameter = 22mm
Difference = [(22 - 5)mm] ÷ 2
17mm / 2 = 8.5mm
Answer:
<h2>B. 468</h2>
Step-by-step explanation:
We have

If |r| < 1, then the formula of a sum of an infinite geometric sequence is:

Substitute:

The answer is 56.5 you take pie times the radius squared
Any number except one greater or equal to 15 or 0.
No one sides can be greater than or equal to the sum of the other 2 sides.
For example, side length 8 would be fine
Answer:
$113.90
Step-by-step explanation:
Find the cost of the meal with sales tax:
90 x 0.075 = 6.525
Add that to the original cost of the meal:
90 + 6.525 = 96.525
Find the cost of the tip:
96.525 x 0.18 = 17.3745
Add the tip to the meal price:
96.525 + 17.3745 = 113.8995
Round to get your final answer
