Find the surface area of the cylinder. Use a ~ 3.14 20 m

lesantik [10]

Answer:

1444.4 m2

Step-by-step explanation:

Surface Area = 2 * 3.14 * (R*R + R*L) = 2 * 3.14 * (10*10+10*13) = 1444.4 m2

Note .. You can Derive this

"Surface Area = 2 * 3.14 * (R*R + R*L)"

Using Calculus by differentiating its Volume

V = 3.14 * R * R * L

2. The Geo Air pilot is looking at SCCA from the plane. From the aircraft the angle of depression is 17 degrees. If the plane is

lana66690 [7]

Answer:

The distance from the plane to SCCA is 34,203.0 feet approximately, and the horizontal distance is 32,708.5 feet approximately.

Step-by-step explanation:

You can draw a right triangle like the one shown in the figure attached, where:

x: horizontal distance.

y: distance from the plane to SCCA.

You can calculate x as following:

$tan\alpha=\frac{opposit}{adjacent}$

Where:

$\alpha=17\°\\opposite=10,000\\adjacent=x$

Substitute and solve for x:

$tan(17\°)=\frac{10,000}{x}\\\\x=\frac{10,000}{tan(17\°)}\\\\x=32,708.5ft$

You can calculate y as following:

$sin\alpha=\frac{opposit}{hypotenuse}$

Where:

$\alpha=17\°\\opposite=10,000\\hypotenuse=y$

Substitute and solve for y:

$sin(17\°)=\frac{10,000}{y}\\\\y=\frac{10,000}{sin(17\°)}\\\\y=34,203.0ft$
