(2x²)³/6x²=(2³)(x²ˣ³) / 6x²=8x⁶/6x²=4x⁴/3
Answer: 4x⁴/3
Answer:
100 pi cm^2
or approximately 314 cm^2
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
The radius is 5
SA = 4 *pi * 5^2
SA = 4*pi(25
SA = 100 pi cm^2
If pi is 3.14
SA = 100 *3.14 = 314 cm^2
Mai is right not to be sure. If you slice across a corner the cross section is a triangle.
Is there answer choices :v
Answer:
r=9
Step-by-step explanation:
6 2
---- = ------
r 3
We can use cross products to solve
6 * 3 = 2 * r
18 = 2r
Divide by 2
18/2 = 2r/2
9 = r
