Answer:
282.7 in²
Step-by-step explanation:
The formula of the surface area of cylinder is "2 times round areas + the height × circumference"
Round area = radius² × π
Circumference = diameter × π
In this case, the surface area is 2×5²×π + 4×10×π ≅ 282.743334
Nearest tenth is 282.7
Answer:
Step-by-step explanation:
The equation of a line is y=mx+b, where m is the slope and b is the y-intercept. y and x are the y and x values of any point respectively.
The information we have:
y = 6
x = -1
m = -3
6 = -3*-1 + b
6 = 3 + b
b = 3
So now we know that m = -3 and b = 3
y and x were 6 and -1 in this case but we need an equation that works for any point on the line so we can keep y and x just as it is (variables, not numbers).
The final equation is:
y = -3x + 3
L= 6+w
6+2w=36
-6 -6
2w=30
w=15; l= 21
15x21= 315
A=315
Answer:
it is 1/2
Step-by-step explanation:
Answer:
Simplifying
y = 2x2 + 20x + 52
Reorder the terms:
y = 52 + 20x + 2x2
Solving
y = 52 + 20x + 2x2
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 52 + 20x + 2x2
