Answer: 28.26
Step-by-step explanation:
What your looking for is called the annulus (or the difference of two concentric circles). You can find the annulus by subtracting the area of the inner circle from the area of the outer circle. Volume of a circle= πr²
You are given the diameter in these problems, so you need radius.
For the first circle (8 in one) :
8/2=4 r=4
A=3.14(4)²
A=50.24
For the second one (10 in one) :
10/2=5 r=5
A=3.14(5)²
A=78.5
To find the measure of the annulus, you subtract those numbers, getting 28.26
Answer:
See below
Step-by-step explanation:
For SIMPLE interest :
1210 + 1210 * .09 * 7 = <u> $ 1972.30</u>
For ANNUAL COMPOUNDING of interest
1210 ( 1 + .09)^7 = <u>$ 2211.93</u>

I do not know which one you need....what are you studying presently?
Since the bolts need to be within 0.2 mm of 12 mm, that means that the length of the bolts are anywhere between 12 mm + 0.2 mm and 12 mm - 0.2 mm.
1. Since they are within 0.2 mm, and since it doesn't specify if they are plus or minus, the bolts can be at lengths anywhere from 12.2 mm to 11.8 mm.
a) Since the bolts are within 0.2 mm of 12 mm, that means that the longest would be 12 mm + 0.2 mm which is equal to 12.2 mm.
b) Since the bolts are within 0.2 mm of 12 mm, the shortest bolt possible would be 0.2 mm smaller than 12 mm, which is equal to 12 mm - 0.2 mm which is 11.8 mm.
