Answer:
314.2in^2
Step-by-step explanation:
GIven data
diameter= 10in
radius= 5in
Height= 2in
The expression for the curved surface area (CSA) of a cylinder is given as
CSA=2πrh
CSA=2*3.142*5*2
CSA=62.84 in^2
The material needed to make one pipe is 62.84in^2
Hence the material need for 5 pipes is
=62.84*5
=314.2in^2
Answer:
y = 1/3x -3
Step-by-step explanation:
Answer:
AB = 11.5mm
Step-by-step explanation:
let the hypotenuse be AC = 23mm
Angle of elevation = 30degrees
Required
Opposite AB
Using the SOH CAH TOA identity
Sin theta = opp/hyp
Sin 30 = AB/AC
Sin 30 = AB/23
0.5 = AB/23
AB = 0.5 * 23
AB = 11.5mm
From what I see B. is 20 but for C I can't see the complete question
Answer:
The answer is option D.
Step-by-step explanation:
cos M = adjacent / hypotenuse
From the picture
b is the adjacent
x is the hypotenuse
so
cos M = b/x
Hope this helps you
