Answer: LAST OPTION.
Step-by-step explanation:
1. You have the following equation:
2. Then you must solve for x, as following:
Therefore, as you can see above, the answer for the exercise is the last option.
The formula for the surface area of a cylinder is:
2<span>π</span><span>r</span><span>h </span><span>+ </span><span>2</span><span>π</span><span>r^</span><span>2
If we substitute in the measurements that we know, you get:
2</span><span>
(3.5) (14) + 2</span><span> (3.5)^2
If we simplify this expression, we get:
98</span><span> + 24.5</span><span>
If you simplify once more, you get
122.5</span><span> or </span><span>≈ 384.85
Therefore, the surface area is 122.5</span> or about 384.85<span>

2<span>π</span><span>r</span><span>h </span><span>+ </span><span>2</span><span>π</span><span>r^</span><span>2
If we substitute in the measurements that we know, you get:
2</span><span>
If we simplify this expression, we get:
98</span><span>
If you simplify once more, you get
122.5</span><span>
Therefore, the surface area is 122.5</span>
