Since 90 degree is 1/4 of a circle, the area will be 1/4 th area of the full circle.
The radius is given by, r = 8 ft, therefore, the area of the full circle is,
Therefore, the area of the sector is,
Answer:
Mean: 4
Median : 4
Mode: 1, 2, 3, 4, 5, 6, 7
Step-by-step explanation:
Measure of center is:
Mean: Average
Median: Middle number
Mode: Often number
Mean: Add all number then divide by the total number in data set.
1 + 2 + 3 + 4 + 5 + 6 + 7 = 28
28/7 = 4
Median: Middle number
1,2,3,4,5,6,7
Mode: most often number
1,2,3,4,5,6,7
<u><em>Kavinsky</em></u>
Because of exterior angles theorem, y=39+65, so y=104
x and y are a linear pair, so they add up to 180. x=180-104, x=76
all angles in a triangle add up to 180, so 21+104+z=180. therefore, z=55
y=104
x=76
z=55
Complementary angles add up to 90.
First angle:x
Second angle:3x
x+3x=90
4x=90
x=22.5
The first angle is 22.5 degrees and the complement is 67.5
