Answer:
30.85
Step-by-step explanation:
circumference of a circle =
In this case, it's half of that because it's a half circle,
With a diameter of 12, the radius is 6
So, = 37.699 then we diver by 2, so we account for the half circle versus a whole. 37.699/2 = 18.8496.
Then add the 12 that makes bottom line. So 18.496 + 12 = 30.8496
Answer:
Step-by-step explanation:
Let that number be . We can build an equation, and solve for
.
less than half of
is
.
more than
is
.
We are given that the two quantities are equal, so we have that .
Adding to both sides gives
.
Multiplying both sides by gives
.
Subtracting from both sides gives
.
Multiplying both sides by gives
.
So, the number is and we're done!
The check is left as an exercise to the reader.
Answer: No
Step-by-step explanation:-
Labeled diameter on the bolt = 0.35 inch
The observed diameter of the bolt= 0.33 inch
For the bolt to be in the package, the percent error must be less than 5%. As the percent error is 6.06% which is greater than 5%, the bolt cannot be in the package.
