2a + 3b, 6ab, And 2b + 3a
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).
For the first one, the fraction version for 0.25 is 1/4 and the percentage is 25%

Answer:
x - 6 = 24
Step-by-step explanation:
1/3 x - 2 = 8
Multiply all the terms by 3
3*1/3x - 2*3 = 8*3
x - 6 = 24
