The equation for volume of a sphere is:
Volume = 4/3 * PI * r^3
r is the radius = 1 inch
Volume is given as 4 cubic inches per second increase.
Given: dv/dt = 4 cubic inches per second.
Need to find dr/dt
Formula for volume of a sphere is: V = 4/3 * π * r^3
so now we have:
4 in^3 = 4 * π *1^2
Divide both sides by 4 * π *1^2
4 in^3 / 4π = 1/π inch per second.
The answer is 1/π inch per second ( exact answer)
or as a decimal: 0.3183 ( round as needed).

Answer:
I'm not sure what you want me to answer from this, so I solved for every variable:
Angle A: 83°
Side b: 6.29
Side c: 5.8
Step-by-step explanation:
-----Angle A:
Since the sum of the interior angles of a triangle ALWAYS equal 180°, we can solve for angle A as follows:
-----Side b:
Here, we use the sin rule for finding sides, since we know all of the angles as well as one side:
-----Side c:
Answer:
yea ur correct
Step-by-step explanation:
use PhotoMath or something like that to check next time, it'll save a lot of time
Answer:
Equations made up of multiple variables like formulas.
Step-by-step explanation:
Similar to how y = mx+b has many letters in it but we can input known values to solve for the values that we want.
