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
Step-by-step explanation:
DG is the total measurement of the line. M is a point inbetween D & G
2x + x - 2 = 7
Simplify. Combine likke terms
(2x + x) - 2 = 7
3x - 2 = 7
Isolate the x. First, add 2 to both sides
3x - 2 (+2) = 7 (+2)
3x = 9
Isolate the x. Divide 3 from both sides
(3x)/3 = (9)/3
x = 9/3
x = 3

3 is your answer for x

(180-x) + 18 + 30 + x/2 = 180
=> 180 + 48 - x + x/2 = 180
=> -x/2 + 48 = 0
=> x/2 = 48
=> x = 48×2 = 96°
