Let's model the problem like a circle.
The circumference of a circle is given by:
Where,
r: radius of the circle.
Clearing the radius we have:
Then, replacing values we have:
Answer:
The best approximation for the radius of the tin is:
Multiply 45 by 2/3 2/3 = 0.66666 so 45*0.6666 = 30

9514 1404 393
Explanation:
A)
Let t and f represent the numbers of two-point and four-point questions, respectively.
__
B) The number of points for each type of question is the product of the point-value per question and the number of questions of that type.
2t + 4f = 100 . . . . . the test is worth 100 points
t + f = 40 . . . . . . . . there are 40 questions on the test
_____
<em>Additional comment</em>
The test will have 30 two-point questions and 10 four-point questions.
