Answer:

Step-by-step explanation:
We know that,

where,
r = radius,
θ = central angle in radian.
Given,
diameter = 6 m, so radius = 3 m.

Putting the values,



X=5 if you solve the equation 20=8x/2
Answer:
360 km^2
Step-by-step explanation:
(this is a rectangular prism)
Volume = length * width * height
Volume = 5 * 6 * 12
Volume = 360 km^2
So we can set up a simple equation for this, where the word “what” is a variable, x. This equation is 3 - x=11. Then we subtract 3 from both sides, giving us -x=8. We can divide both sides by -1, giving us x=-8. The answer would be -8. Hope this helped.
