Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank)

Answers

Answer:

volume = 254.34 cubic inches

Step-by-step explanation:

r = diameter /2 = 6/2 = 3 in

h = 3 × r = 3 × 3 = 9

volume = pi× r^2 × h

3.14 × 3 × 3 × 9254.34 cubic inches..

A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bulbs would the robot be expected to find in a batch of 15 bulbs?

Answers

Answer:

Step-by-step explanation:

Given that:

Flawed bulbs = 4

Not flawed = 26

Total examined = (flawed + not flawed)

Total examined = (4 + 26) = 30

P(flawed) = flawed / total

P(flawed) = 4 / 30 = 0.1333333

If 15 is examined :

Expected number of flawed bulbs :

(4/30) * 15 = 2

A -foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a angle with a short vertical support.

Answers

Complete question :

A 25-foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a 65∘ angle with a short vertical support.

What is the length x of a diagonal support, to the nearest tenth of a foot?

Answer:

13.80 feets

Step-by-step explanation:

Taking either of the triangles formed and attached to the picture, the length of diagonal, x can be obtained using Pythagoras rule :

To obtain x :

Sinθ = opposite / hypotenus

Opposite = 12.5 feets ; hypotenus = x ; θ = 65°

Sin 65 = 12.5 / x

0.9063077 * x = 12.5

x = 12.5 / 0.9063077

x = 13.792225

x = 13.80 feets

Answer:

x=1

Explanation:

3x+4*2x=11

(We move all terms to the left)

3x+4*2x-(11)=0

( We multiply elements )

3x+8x-11=0

(We add all the numbers together, and all the variables )

11x-11=0

( We move all terms containing x to the left, all other terms to the right )

11x=11

x=11÷11

x=1

In ΔMNO, n = 92 inches, ∠N=119° and ∠O=20°. Find the length of m, to the nearest 10th of an inch.

Answers

Answer:

Step-by-step explanation:

The length of the side of the triangle will be 69 inches.

What is the sine law?

The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.

The sine law in the triangle ΔMNO is given as,

n / sin N = m / sin M = o / sin O

The third angle is calculated as,

∠M + ∠N + ∠O = 180°

∠M + 119° + 20° = 180°

∠M = 41°

The length m is calculated as,

n / sin N = m / sin M

92 / sin 119° = m / sin 41°

m = 69 inches

The length of the side of the triangle will be 69 inches.
