12 more games.
The current winning percentage is 60%, which is found by dividing 12 by 20 and multiplying by 100 (12 / 20 = 0.60, 0.60 x 100 = 60).
To get a winning streak of 75%, Anne has to win 12 more games in a row. That will mean she will have won 24 out of a total of 32 matches, and this decimal is equal to 0.75. Multiply by 100 to get the percentage of 75%.
A because if he started at negative ten you would add the 10 he increased. When you add those two together you get 0.
-10+10=0
Answer: 105.84 cm^2
To find the answer, first you have to start by finding the percent of the circle in the sector. Convert the radians given to 108 degrees. 108 out of 360 is 30%.
Now, find the area of the circle. It's pi x r^2, so the area is 352.810.
Multiply this by 30% to find our area of 105.84 cm^2
