The required relength is half of the length of AC
AC = sqrt(8 - (-2))^2 = 8 + 2 = 10
Therefore, the required length is 5.
Answer:
1.6%
Step-by-step explanation:
2376/2338= 1.016
1.016-1 = .016 * 100
1.6%
hope it helps :)
Answer:
The area of the sector is 3pi/2
Step-by-step explanation:
A sector is that part of a circle bounded by 2 radii and an arc
The circle has an area of 9 pi with a central angle of 60 degrees.
Now the area of the sector is pretty much straight forward to calculate. Since it is a circle, the total angle we have is 360.
Now the sector subtends an angle of 60 degrees at the centre. What this means is that the sector is exactly 1/6 of the circle. meaning that cutting the circle into 6 slices will give the sector.
Thus, the area of the sector is one-sixth the area of the circle.
The area of the sector is thus 1/6 * 9pi = 9pi/6 = 3pi/2 or 3/2 pi
