Hi there!

The formula for the lateral area of a cylinder is LA = 2 x pi x r x h. Using this formula, we can plug in the given values and solve for the lateral area.

WORK:
LA = 2pi x r x h
LA = 2pi x 4.5 x 17
LA = 153pi mm^2

The correct answer is the first option - 153pi mm^2

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Carson uses cubes to make a pattern of shapes. The first shape has a height of

Aliun [14]

Answer:

The total number of cubes in each shape will alternate between even and odd.

The length of each shape will alternate between even numbers and odd numbers

Step-by-step explanation:

I have drawn a picture of the cubes below.

The cubes for Step 1 are black.

Those added in Step 2 are pink.

Each step has cubes of a different colour.

$\begin{array}{cccc}\textbf{Step} & \textbf{Height} &\textbf{Length} & \textbf{Cubes}\\1& 2 & 2 & 2\\2 & 3 & 3 & 9\\3& 4 & 4 & 16\\4 & 5 & 5 & 25\\5 & 6 & 6 & 36\\\end{array}$

The total number of cubes in each shape (Column 4 in the table) alternates between even and odd.

The length of each shape (Column 3 in the table) alternates between even and odd.

Solve for w.<br> V+w/2=a

lara31 [8.8K]

Answer:

w = 2(a - V)

Step-by-step explanation:

Let's first eliminate the fraction by multiplying all three terms by 2:

2V + w = 2a

Next, isolate w by subtracting 2V from both sides:

w = 2a - 2V, or w = 2(a - V)
