Answer:
314.16 in²
Step-by-step explanation:
If the diameter is 20", then the radius is 10" (1/2 the diameter).
Area of a circle is ²
So, π 10² = 100π = 314.16 in²
Answer:
3x2 + 2x3 + 2x1 =14
Step-by-step explanation:
3x2 = 6 +
2x3 = 6 +
2x1 = 2 =
14
First we simplify the inequality
1. <em>multiply 6 by the other side of the inequality (-4) </em>
Now we have ...
a > -24
Anything that can be a solution to the inequality <u>must be greater than -24</u>
-18 is greater than -24
This means that, YES! a = -18 IS a solution to the inequality
1 1/2 is the correct answer
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
