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
Answer:
14.8-16x
Step-by-step explanation:
2x+14-18x+0.8
14.8-16x
To solve this problem, we must figure out what percent of the total spending was spent on mommy and baby exercise programs. To figure this out, we should divide how much was spent on the mommy and baby exercise by the total amount spent on the district activities.
$1430/$5720 = 0.25
This is a percentage, or a portion out of 100, which means we must multiply this decimal by 100 to find its equivalent percentage.
0.25 * 100 = 25
Therefore, your answer is 25% of the total spending was spent on mommy and baby exercise programs.
Hope this helps!
To do this multiply 1 by 4, then 3 by 5. 4 over 15 is your answer.
