Lets put out the 4 because it can also be pulled out of 12
4(d+3)
Hope This Helps!
Answer: ![\frac{11}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B12%7D)
Step-by-step explanation:
Since we are looking for the total fraction completed , all we need do is to add the fraction completed last month and the fraction completed this week , that is
+ ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
The L.C.M is 12 , so we have
+
=![\frac{8 +3}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B8%20%2B3%7D%7B12%7D)
= ![\frac{11}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B12%7D)
Therefore 11/12 is completed
Answer:-5
Step-by-step explanation:
The area is 81*pi-162. Look at the triangle formed by the chord and the two radii connected to the endpoints of the chord. Since 18^2+18^2=(18*\sqrt2)^2, this is an isosceles right triangle by Pythagorean theorem. The area of the quarter circle containing the region we look for is pi*18^2/4=81*pi. The area of the right triangle is 18*18/2=162. The difference between these two areas, or 81*pi-162, is the area of the smaller region.
