What is the volume of a sphere with a radius of 4.5 inches?
schepotkina [342]

Answer:

D 381.7 in^3

Step-by-step explanation:

V=4/3pi r^3

V=4/3pi 4.5^3

4/3x3.14x4.5x4.5x4.5

It is approximately 381.51 when you use 3.14 as pi. This is closest to answer D, so I would assume it is that.

Sorry, I thought it said circle at first.

There are four steps in the manufacturing process of a stuffed toy: cutting, stuffing, sealing, and packaging. There are two emp
Anit [1.1K]

Answer:

(a) 2min/15units

(b) 1min/20units

(c) The bottleneck stage is cutting. The process capacity is 450units/hour

(d) The capacity of the new employee should be 1unit/2sec. The process capacity will increase four times

Step-by-step explanation:

(a) Cycle time for stage cutting for 2 employees = 16sec/2units × 1min/60sec = 2min/15units

(b) Cycle time for stage sealing for 1 employee = 3sec/1unit × 1min/60sec = 1min/20units

(c) Process capacity of stage cutting = 15units/2min × 60min/1hour = 450units/hour

(d) If the capacity of the new employee is 1unit/2sec, the process capacity = 1unit/2sec × 3600sec/1hour = 1800units/hour. The process capacity increases 4 times (1800/450 = 4)
