Answer:

$A=376.99\ units^2$

Step-by-step explanation:

By definition, the surface area of a cylinder is given by the following formula:

$A = 2\pi r h + 2\pi r ^ 2$

Where r is the radius and h is the height.

In this case, we have to:

$r = 4\\\\h = 11$

then the surface area is:

$A = 2\pi(4)(11) + 2\pi(4) ^ 2$

$A=120\pi$

$A=376.99\ units^2$

For 6 consecutive days, Alejandro studied for 5 minutes more each day than he did the previous day. Which best represents the ch

Andreyy89

Let's say the first day he studied for x minutes.
Each day he studies 5 more minutes than his previous day.
Day 2: x +5
Day 3: x + 10
Day 4: x + 15
Day 5: x + 20
And finally the last day: x + 25

To find the difference all u need to do is take the amount he studied on the first day and subtract it by how much he studied the last day.

X - X + 25
Which gives u a difference of 25
