P=10
Explanation
2p+p+90+100+140=360
3p+330=360
-330. -330
3p=30
P=10

Answer:
8.6 in²
Step-by-step explanation:
The area of the entire circle is A = πr², or A = π(2 in)².
This corresponds to a central angle of 2π radians, or 6.28 radians.
The area of the sector described above is just a certain fraction of that:
4.3 rad
-------------- * Area of circle = 0.685(4 * 3.14) = 8.6 in²
6.28 rad
Answer:
The volume is:
cubic units
Step-by-step explanation:
Volume of a solid:
The volume of a solid, given by the function f(x), over an interval between a and b, is given by:

y = x, y =1, x = 0
This means that the upper function is y = 1, and the lower function is y = x. So

The lower limit of integration is x = 0.
The upper limit is y = x when y = 1, so x = 1.
Then
