because it's D
We have to find the volume of oblique cone. An oblique cone is a special type of cone in which the apex is not located directly above the center of the circular base, so it looks like a slanted cone.
Volume of oblique cone = 
where 'r' is the radius and 'h' is the height.
Here r = 6 cm and h = 10 cm
Volume = 
= 
= 
So, the volume of the given oblique cone is
.
Option 4 is the correct answer.
3x + 4y = 0
3x = -4y
x = 4y/3
5x - 6y = -38
(5*4y/3) - 6y = -38
(20y/3) - 6y = -38
(20y - 18y) / 3 = -38
2y = -114
y = -57
x = 76

-20 = 4a - 2b + c
-4 = c
-20 = 16a + 4b + c
4a - 2b + c = 16a + 4b + c
4a - 2b = 16a + 4b
-6b = 12a
b = -2a
-20 = 4a - 2b + c
-20 = 4a + 4a - 4
-16 = 8a
-2 = a
b = 4
c = -4
y = -2x^2 + 4x - 4
y = -2 * (x^2 - 2x) - 4
y = -2 * (x^2 - 2x + 1 - 1) - 4
y = -2 * (x^2 - 2x + 1) + 2 - 4
y = -2 * (x + 1)^2 - 2 </span>
