Answer:
1,172.3 cm³
Step-by-step explanation:
Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is
V = (πd²/4)h
d = 4 cm
h = 20 cm
Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.
Add
20 + 4 = 24
Then
28,134.4 ÷ 24 = 1172.26
Rounded to the nearest 0.1 or the Tenths Place = 1,172.3
Therefore, 1,172.3 rods will be made per hour.
Answer:
5 and 61
Step-by-step explanation:
Using Pythagoras' identity in the right triangles
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
(1)
c² = a² + b² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )
c = 
= 5
(2)
c² = a² + b² = 11² + 60² = 121 + 3600 = 3721 ( take the square root of both sides)
c = 
= 61

Answer:
the first term is 4
Step-by-step explanation:
Given
G(3) = 36
G(6) = 972
Solution:
General formula for geometric series
G(x) = AB^x
From given data: G(6)/G(3) = 972/36 = 27
From formula: G(6)/G(3) = AB^6/(AB^3) = B^3
Therefore
B^3 = 27
B=3
Hence
G(1) = AB^1 = AB^3/B^2=36/3^2=36/9=4
Ans: the first term is 4
