Answer:
3V
r = ∛ ( ---------- )
4π
Step-by-step explanation:
Please, enclose the fraction 4/3 inside parentheses, to eliminate any possibility of misreading this fraction. Also note that this formula MUST include "pi," symbolized by π.
V = (4/3) π r³ This formula does NOT include "m," which is a unit of measurement, not a variable.
Our task is to solve this formula for the radius, r.
Divide both sides by (4/3) π, to isolate r³. This results in:
v (4/3) π r³
------------- = -----------------
(4/3) π (4/3) π
V 3V
Then r³ = -------------- = --------
(4/3) π 4π
and r is found by taking the cube root of the above result:
3V
r = ∛ ( ---------- )
4π

Answer:
x = 6
Step-by-step explanation:
Triangle BCD: cos(60) = x/BC => BC = x/cos(60)
Triangle ABC: sin(45) = BC/6√2 => BC = (6√2)sin(45)
so x/cos(60) = (6√2)sin(45)
x/(1/2) = (6√2)(√2/4)
x/2 = 12/4
x = 2(3)
x = 6
