It's unclear what the planes are supposed to be, so I'll take
and
with
.
The cross sections are disks with diameter
, so each disk of thickness
has a volume of

Then taking infinitesimally thin disks, we find the solid has a volume of

Since

and


it follows that the volume is



Answer:
Step-by-step explanation:
a = 180 - 2(19) = 142°
b = 90° Triangle in a circle with one side as a diameter makes right triangle
c = 2(19) = 38°
d = 38°
e = 38°
f = 19° alternate angle
g = 19° equilateral triangle
h = 90 - 19 = 71°
Answer:
a = -5
Step-by-step explanation:
Answer:
- x^2+y
- 3(n-7)
- 37x-9.85
Step-by-step explanation:
1. If x represents a number, then x^2 represents its square. If y represents a second number, then the sum of that square and the second number is ...
x^2 + y
__
2. The difference of a number (n) and 7 is (n-7). Three times that difference is ...
3(n - 7)
__
3. If x represents a number, then the product of 37 and a number is 37x. 9.85 less than that is ...
37x - 9.85
Answer:
The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.
Hope it helps.
