Answer:
Help
Step-by-step explanation:
Remember: The formula for surface area for cylinders are S= 2πrh + 2πr²
The 2πr² represents the circular parts of the cylinder.
First, let's find the lateral side of the cylinder.
→ 2 (3.14)(6)(15) = 565.2
Next, find the circular parts.
→ 2 (3.14)(6²)
→ 2 (3.14)(36) = 226.08
Add the two answers together.
→565.2 + 226.08 = 791.28
Round.
Your final answer is 791.3 in²
I hope this helps!
Just a generic answer would by 12/8 or any other multiple of the numbers. If that is a fraction than same goes as above.
Hello.
The answer is: (x−4)(x−6)
Factoring means we want something like
(x+_)(x+_)
We need two numbers that...
Add together to get -10
Multiply together to get 24
Try -4 and -6:
-4+-6 = -10
-4*-6 = 24
Fill in the blanks in
(x+_)(x+_)
with -4 and -6 to get...
(x-4)(x-6)
Have a nice day
Answer: 28 cm
Step-by-step explanation:
x - the length of the shorter piece
2x - the length of the longer piece
Together they are 42 cm long.
Compose te equation:
2x + x = 42
3x = 42
x = 14 cm
The shorter piece is 14 cm, the longer piece is twice longer, 2x, or 2( 14 ).
Two times longer than 14 is 28. The longer piece is 28 cm.
