Answer:
The correct answer to the exercise is:
- Surface area of a circle = 633.1
Step-by-step explanation:
To obtain the surface area of a circle, you can use the formula:
- Surface area of a circle = π *
Where:
- π = 3.14 (the exercise give this)
- r = Circle radius.
How you can see, in the picture gives you a straight line that passes through the circle side by side, the circle radius is half of that value, then:
- r = 28.4 mm / 2
- <u>r = 14.2 mm</u>
Now, we can replace the values in the first formula:
- Surface area of a circle = π *
- Surface area of a circle = 3.14 *
- Surface area of a circle = 3.14 * 201.64
- Surface area of a circle = 633.1496
- Surface area of a circle = 633.1 (rounded to the nearest tenth).
The area is 100 because 15*B(9)=100
To solve this one you just need to add all of the minutes each student said, then you can divide them by the total number of students and that would be the mean travel time of students
