Find the height of a cylinder with a surface area of 1,206.4 in^2 and a radius of 8 in.

fgiga [73]

Answer:

h = 16 inches

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2 pi rh

We know the surface area and the radius

1206.4 = 2 ( 3.14) * 8^2 + 2 * 3.14 * 8 *h

1206.4 = 401.92+50.24h

Subtract 401.92 from each side

1206.4-401.92 = 401.92-401.92+50.24h

804.48=50.24h

Divide each side by 50.24

804.48/50.24 =50.24h/50.24

16.01273885=h

A cube has a volume of 125 in3. find the side length of this cube in inches.

Novay_Z [31]

Answer:

5 inches

Step-by-step explanation:

The formula for a cube's volume is its side length cubed. So to get the side length when given the volume, you can take the cube root of the volume. $\sqrt[3]{125} = 5$ inches.

Howard is standing 109 yards from the bottom of a water reservoir. He estimates that the angle of elevation to the top of the wa

pav-90 [236]

Answer:

70.1 yards

Step-by-step explanation:

See the attached diagram.

Let AC is the reservoir with A as the bottom and C is the top.

Now, B is the position of Howard which is 109 yards from A i.e. AB = 109 yards.

Again, the angle elevation from B to C is 50 degrees.

So, ∠ ABC = 50°

Now, $\cos 50 = \frac{AB}{BC} = \frac{109}{x}$

⇒ x = 109 cos 50 = 70.1 yards.

Therefore, the distance between the top of the reservoir and Howard i.e. BC is equal to 70.1 yards. (Answer)
