Step-by-step explanation:
Here, given:
The volume of the sphere = cubic units ... (1)
Also, radius of the sphere = x units
Now, VOLUME OF SPHERE =
So, volume of a sphere with radius x =
But volume of sphere is given by (1).
Hence, radius of the sphere = 5 units.
Answer:
C
Step-by-step explanation:
you only need to have some racional skills, but if you get the cos. of the little triangle to then have the value of x, you can know that the value of DE is 38.

Answer:
x=-4, y=2. (-4, 2).
Step-by-step explanation:
5x+6y=-8
-2x+8y=24
-----------------
2(5x+6y)=2(-8)
5(-2x+8y)=5(24)
-----------------------
10x+12y=-16
-10x+40y=120
---------------------
52y=104
y=104/52
y=2
5x+6(2)=-8
5x+12=-8
5x=-8-12
5x=-20
x=-20/5
x=-4
