$120 and the ratio is 3:2
$200 6:4 and half
Surface Area of a cylinder 2(π•r²)+(2π•r)•h
So
If the diameter is 8 then the radius is 4. the height is 5.
so you have, 2(3.14•4²)+(2•3.14•4)•5
solve. PEMDAS
Parentheses & Exponents first.
2(3.14•16)+(2•3.14•4)•5
2(50.24)+(6.28•4)•5
2(50.24)+(25.12)•5
Multiplication & Division second (left to right)
100.48+125.6
Add & Subtract (left to right)
226.08cm
Answer:
The solution x = 
Step-by-step explanation:
<u>Step 1</u>:-
Given 
we have to use formula 
=
Again by using formula 
so 
<u>step 2:</u>-
The solution of given problem is 
A + C
(-5, -7) is 7 units to the left of point H
(-7, 7) is more than 7 units up and left of point H
the x axis is at (infinity, 0), being only 7 points up from point H
(x + 5/2 * 2/5)^2 = -5/2
(x)^2 sqrt 2 = -5/2 sqrt 2
(x) = i sqrt10/2 - 5/2, i sqrt10/2 - 5/2
