Answer:

351.9 m²

Step-by-step explanation:

SA=2\pi r^2+2\pi rh where r is the radius of the base and h is the height of the cylinder

We're given the diameter of the base, which is 8 m. Therefore, the radius is 4 m (after dividing by 2).

Plug in 4 as r and 10 as h

SA=2\pi (4)^2+2\pi (4)(10)\\SA=2\pi (16)+2\pi (40)\\SA=32\pi +80\pi \\SA=112\pi

Therefore, the surface area of the cylinder is approximately 351.9 m² after rounding to the nearest tenth.

I hope this helps!

The equation of the red graph, g(x) is g(x) = |x| - 5

<h3>How to determine the equation of the red graph, g(x)?</h3>

The graph that completes the question is added as an attachment

The function f(x) is given s:

f(x) = |x|

From the attached graph, we can see that the function f(x) is shifted 5 units down to get to g(x).

This means that:

g(x) = f(x) - 5

Substitute f(x) = |x|

g(x) = |x| - 5

Hence, the equation of the red graph, g(x) is g(x) = |x| - 5

Suppose f(x)=x^2 find the graph of f(x)+1
Kisachek [45]

Answer:

f(x)+1 = x^2 + 1

Step-by-step explanation:

The graph of f(x)+1 will be given by adding 1 to the initial function f(x)

f(x)+1 = x^2 + 1

See the attachment for the graph;
