This value is easily converted to a decimal number by multiplying numerator and denominator by 2:
(373×2)/(500×2) = 746/1000 = 0.746
_____
You can also divide 373 by 500 using a calculator to get the decimal result.
Answer:
Length of pipe = 21 cm
Internal diameter = 4 cm
Internal radius = \frac{4}{2} = 2 cm24=2cm
Thickness = 0.5 cm
Outer radius = 2+0.5=2.5 cm
Volume of pipe =\pi R^2 h - \pi r^2 hπR2h−πr2h
Volume of pipe =\frac{22}{7} (2.5)^2 (21)-\frac{22}{7}(2)^2(21)=148.5 cm^3
=\frac{22}{7} (2.5)^2 (21)-\frac{22}{7}(2)^2(21)=148.5 cm^3722(2.5)2(21)−722(2)2(21)=148.5cm3
Hence The volume is 148.5 cubic cm.

The thickness of a metal pipe is 1.5cm. The inner diameter is 21cm. What is the volume of metal required for a pipe of length 7cm
Answer:
39 ib or pounds
Step-by-step explanation:
easy
ABC ~ A’B’C’
So, AB=A’B’ , BC=B’C’ , AC = A’C’
Given, AB=15 and A’C’=4
So, AC = 4 , A’B’ = 15
Answer:
The 3rd option
Step-by-step explanation:
The pattern is every 2 hours is $15 so 4 hours would be equal to $30
Since 4 hours would equal 30 and we need 12 hours multiplying both numbers by 3 would get you the answer
4x3=12
30x3=90
Making it equal
