For the first one the answer is B
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:
He will sell 70 bags of popcorn and 105 bottles
Step-by-step explanation:
In 1 day he sells 14 bags of popcorn and 21 bottles
Multiply 14 by 5 which is 70
then multiply the bottles which is 21 by 5 days
105
He will sell 70 bags of popcorn and 105 bottles
They can carry 80 containers each
160,000 / 2,000 = 80
