Answer:
The correct answer to the exercise is:
- Surface area of a circle = 633.1
![mm^{2}](https://tex.z-dn.net/?f=mm%5E%7B2%7D)
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 *
![(14.2 mm) ^{2}](https://tex.z-dn.net/?f=%2814.2%20mm%29%20%5E%7B2%7D)
- Surface area of a circle = 3.14 * 201.64
![mm^{2}](https://tex.z-dn.net/?f=mm%5E%7B2%7D)
- Surface area of a circle = 633.1496
![mm^{2}](https://tex.z-dn.net/?f=mm%5E%7B2%7D)
- Surface area of a circle = 633.1
(rounded to the nearest tenth).
