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:
20/54
Step-by-step explanation:
Answer:
is this is ur online test ????
To find the value of "x", you need to isolate/get the variable "x" by itself in the equation:
4x - 1 = 6 Add 1 on both sides
4x - 1 + 1 = 6 + 1
4x = 7 Divide 4 on both sides to get "x" by itself
Now that you know the value of x, you can find 24x:
24x Substitute/plug in 7/4 into "x" since x = 7/4

Answer:
61 c
Step-by-step explanation:
Circumference= 2πr = πd=3.14d
- 25 c, d = 24.3 mm ⇒ C=24.3*3.14 = 76.302
- 10 c, d = 17.9 mm ⇒ C=17.9*3.14 = 56.206
- 5 c, d = 21.2 mm ⇒ C=21.2*3.14 = 66.568
- 1 c, d = 19.1 mm ⇒ C=19.1*3.14 = 59.974
1*10 c+ 2*25 c+ 1*1 c = 61 c
