Answer:
36.575
Step-by-step explanation:
you need to find line ab you can do 
for the triangle and get the line you also need to get the squar root of it as it is still squared then devide by 2 to get the rades then times that by pi and there you go you have the area also sorry for spelling I love math not English
Answer:
he has 0.66 of fabrics remaining, 0.66 can be 33/50
Step-by-step explanation:
Given: The given function is
To find: Here we need to find the value of c for which f(x,y) will be a joint
discrete probability density function.
Solution:
Now, to find c we have,
![\int\limits^3_{-2} \,\int\limits^2_0 {f(x,y)} \, dx dy\\=\int\limits^3_{-2} \,\int\limits^2_0 {c(x-y)} \, dx dy\\\\=\int\limits^3_{-2} \,[2c-2cy]dy\\=10c-5c\\=5c\\The integral should be1.\\So, 5c=1\\](https://tex.z-dn.net/?f=%5Cint%5Climits%5E3_%7B-2%7D%20%5C%2C%5Cint%5Climits%5E2_0%20%7Bf%28x%2Cy%29%7D%20%5C%2C%20dx%20dy%5C%5C%3D%5Cint%5Climits%5E3_%7B-2%7D%20%5C%2C%5Cint%5Climits%5E2_0%20%7Bc%28x-y%29%7D%20%5C%2C%20dx%20dy%5C%5C%5C%5C%3D%5Cint%5Climits%5E3_%7B-2%7D%20%5C%2C%5B2c-2cy%5Ddy%5C%5C%3D10c-5c%5C%5C%3D5c%5C%5CThe%20integral%20should%20be1.%5C%5CSo%2C%205c%3D1%5C%5C)
∴
Therefore, the required value of c is 1/5.
185.4m (rounded to 1dp)
Circumference of a circle is the diameter times by pi. 59×pi=185.4
