Answer:

Step-by-step explanation:

The formula for the volume of a cone is

V = (1/3)r²h, where r is the radius and h is the height.

Unfortunately, you seem to have given the diameter twice.  

Which is the diameter of the base, 6 inches or 4 inches?  What is the height of the cone, in inches?

Natalka [10]

Answer:

(29.14 ; 30.06)

Step-by-step explanation:

Given that'

Sample size (n) = 57

Mean (m) = 29.6

Population standard deviation (σ) = 2.7

Confidence interval = 80%

= (1 - 0.8) / 2 = 0.1

Mean ± z * σ/√n

Using the Z probability calculator : Z0. 1 = 1.28

Hence,

29.6 ± 1.28 * (2.7 / √57)

29.6 - (1.28 * 0.3576237) ; 29.6 + (1.28 * 0.3576237)

29.142241664 ; 30.057758336

(29.14 ; 30.06)

SOMEONE HELP ME ASAP PLZZ!!!
Black_prince [1.1K]

Answer:

The distance of the plane from the base of the tower is 25.5 foot.

Step-by-step explanation:

As given

Max is in a control tower at a small airport.

He is located 50 feet above the ground when he spots a small plane on the runway at an angle of depression of 27°.

Now by using the trigonometric identity.

tan\theta = \frac{Perpendicular}{Base}

As shown in the figure given below

Perpendicular = CB

Base = AC = 50 feet

\theta = 27^{\circ}

Put in the identity.

tan\ 27^{\circ} = \frac{CB}{AC}

tan\ 27^{\circ} = \frac{CB}{50}

tan\ 27^{\circ} = 0.51\ (Approx)

Put in the above

0.51 = \frac{CB}{50}

CB = 0.51 × 50

CB = 25.5 foot

Therefore the distance of the plane from the base of the tower is 25.5 foot.
