The area of the entire circle is pi*(7)^2, or 49pi.
Due to the 90 degree angle, the area of the larger blue sector is
90
------- * 49 pi = 49/4 units^2
360
The area of the smaller blue sector is
48
------- 49 pi = (2/15)(49 pi) = 98 pi/15 units^2
360
The total area of the blue sectors is the sum of 98 pi/15 and 49 pi/4 (units^2):
59 units^2
Answer:
±0.06
Step-by-step explanation:
The range is 0.28 - 0.16 = 0.12. So half of that is 0.06.
I hope this helps you
1/4+3/7
7/7.4+3.4/7.4
7/28+12/28
19/28
(0,a)
it didnt move left or right on the x-axis
it went up a units (since its half of 2a)
To figure this out, you need to figure out what percentage 68 is of 85.
1. Divide 68 by 85 (Divide the % correct by the total number of questions)
2. 68/85 is .8, which is 80%
