A quarter has a diameter of approximately 24 millimeters. What is the approximate area of the quarter ?
Answer choices:
75.36 mm square
452.16 mm square
150.72 mm square
1,808.64 mm square
Answer: 452.16
Step-by-step explanation: The formula for area is A=πr². The radius is half of the diameter, which would give us 12. so just plug in. 12² is 144. 144π is 452.38. (Which is close to 452.16) Hope this helps :)

Answer:
11 is 405, 12 is 107.5, 13 im not sure of
Step-by-step explanation:
First on 11 you can just do 21*21 (the big square) and subtract that by 36 (which is 6*6, the small square), you'll get 107.5.
Then on 12, it is made up of a large rectangle, a small triangle, and a flatter triangle. The top triangle's formula is 1/2(7*3) which = 10.5. The big rectangle is 13*7 = 91. The last triangle is 1/2(4*3) which = 6. It is 3 because 13-10. Add all those up and you should get 107.5.
And I just want to know on number 13 if that 11 is the radius or diameter. I can't seem to tell.

Step-by-step explanation:
Line them up from least to greatest
1.25, 1.50, 1.75, 2.25, 2.50, 2.75
Find the middle number. The middle two number are 1.75 and 2.25. Add them up, which will equal 4. Divide up 4 by 2 which would equal 2. So the median cost of the popcorn during this period is $2.

Four runners completed in a 10-kilometer relay race. Each Runner ran the same distance. What was that distance?
Answer:
each runner ran 2.5 kilometers
Step-by-step explanation:
10÷4=2.5
The distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.
What is division?A method of dividing something into equal parts is called division. It produces a fair distribution of resources and is one of the four basic operations in mathematics.
How to solve this problem?Total distance = 10 kilometers
Total number of runners = 4
Since they all covered the same distance,
the distance = 10/4 = 2.5 kilometers
Therefore, the distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.

Answer:
Step-by-step explanation:
we have to find if the series have a constant of proportionality by dividing the value of y by each value of x
1)
100 : 2 = 50
200 : 4 = 50
300 : 6 = 50
400 : 8 = 50
ok = y
2)
0.60 : 4 = 0.15
1.20 : 8 = 0.15
1.44 : 12 = 0.12
no = n
3)
0.15 : 1 = 0.15
0.3 : 2 = 0.15
0.45 : 3 = 0.15
0.6 : 4 = 0.15
ok = y
