The last step in a proof contains the conclusion
18 - 5.7 = 12.3
12.3 - 8.8 = 3.5
3.5 to a fraction = 3 1/2
So the answer = 3 1/2
Hope this helps >.<
Common factors are 1,2,4 so the greatest one would be 4
Choices that should have been accompanied this problem were:
* 19.6 square units
* 39.3 square units
* 7.85 square units
Given:
OA = 5
Length of AB/Circumference = 1/4
Area of sector AOB:
3.14(5²)/4 = 3.14 (25) / 4 = 78.5/4 = 19.625 or 19.6 square units.
