Answer:
volume of the solid = 
Step-by-step explanation:
As given , the region : |x| + |y|
1
when y
0 ,
|x| + y = 1
⇒|x| = 1 - y
when y ≤ 0 ,
|x| - y = 1
⇒|x| = 1 + y
The given region is the rectangle with sides (0, 5) , (0, -5), (5, 0), (-5, 0)
As given , the vertical cross section are semicircle
As we know that the area of semi circle = 

Now,
Volume =
+ 
=
- 
=
[1-0] -
[0-1]
= 
⇒volume of the solid = 
Answer:
B
Step-by-step explanation:
Answer:
arc AB = 3.14 in
Step-by-step explanation:
circumference of full circle = π2r = (3.14)(2)(6) = 37.68 in
arc AB = (30°/360°)(37.68) = 3.14 in
