Answer:
53.38ft
Step-by-step explanation:
By it asking the length of the pathway, in math terms its just asking you the circumfrence of the pond.
C = 2(
)(r)
C = 2(3.14)(17/2)
C = 2(3.14)(8.5)
C = 53.38ft
Answer:
21 box of books can be brought up by the delivery person at one time
Step-by-step explanation:
Here, we want to know the number of box of books that the delivery person could bring up at one time.
Let the number of boxes be x , so the total mass of the boxes that could come up at a time will be x * 40 = 40x lb
Let’s add this to the mass of the delivery person = 150 lb
So the total mass going inside the lift would be 150 + 40x
So we have to equate this to the maximum capacity of the lift;
150 + 40x = 1020
40x = 1020 - 150
40x = 870
x = 870/40
x = 21.75
Now since we cannot have fractional boxes, the number of boxes that could come into the lift without exceeding the maximum capacity of the lift is 21
Answer:
Step-by-step explanation:
The idea is to find out how much steel it takes to make 1 rod, then multiply that amount by 192. The amount of steel in a rod is found in the volume of steel in each rod. The formula for the volume of a cylinder is
For us this formula looks like this:
which, in terms of pi, is 240π. That's not a very useful measure, so rounded to the nearest whole number, each rod take 754 cubic centimeters of steel. Multiply that by 192 and you get that you need
144,768 cubic centimeters of steel to make 192 rods of that size.
