Answer:
<h2>652 ft²</h2>
Step-by-step explanation:
Look at the picture.
It's a net of right rectangular prism.
We have three pairs of rectangles:
7ft × 8ft
7ft × 18ft
8ft × 18ft
The formula of an area of a rectangle l × w:
A = lw
Calculate the areas:
A₁ = (7)(8) = 56 ft²
A₂ = (7)(18) = 126 ft²
A₃ = (8)(18) = 144 ft²
The Surface Area :
S.A. = 2A₁ + 2A₂ + 2A₃
Substitute:
S.A. = 2(56) + 2(126) + 2(144) = 652 ft²
Use PEMDAS:
P = parenthesis
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
First, start with the parenthesis:
(8.76 * 109)(6.52 * 10 - 3) / 13.27 * 105
(954.84)*(62.2) / 13.27 * 105
Then do ALL multiplication:
59,391.048 / 1,393.35
Now do all division:
42.62
So, your final answer is 42.62
Surface area of cylinder = 2 x pi x r x h + 2 x pi x r*2
So 2 x pi x 4 x 11 + 2 x pi x 4*2 = 376.99
In this pattern, we're subtracting 3, so after -4, we'd get -7, -10 and -13, which would be option A
19/45 is 0.42222222 if you round that to the nearest thousandth you get 0.422.
