Answer: 154 cu. in
Step-by-step explanation:
The space you have to measure is a cylinder.
Its height is the same as the height of the pipe, 16 inches.
Its diameter =inner diameter of pipe
= outer diameter of pipe - thickness of walls at each end of diameter
= 6 - 2(1.25)
= 3.5 inches
radius r = 1.75 inches
A cross-section of the cylindrical space is a circle.
area of circle = πr² = π * 1.75² = 9.625
volume = area of circle * height
9.625 * 16
= 154 cu. in.
Answer:
2
Step-by-step explanation:
y = 2x +7
so,
if x=0 then y =2 x 0 +7 =7
if x=1 then y =(2 x1) +7 =2+7=9
if x=2 then y =(2 x2)+7 = 4+7 =11
if x=3then y =(2 x3) +7 = 6+7 =13
if x=4 then y =(2 x4) +7 =8+7 =15
if x=5 then y =(2 x5) +7 = 10+7 =17
Rational because you can write that as 39/1, and irrational numbers cannot be written as fractions.
The answer should be -0.6
