PtichkaEL [24]

Answer:

Initial Amount=1

Decay Factor=0.99987

Decay Rate=0.013%

Step-by-step explanation:

If P = 0.99987ᵃ

I. Initial amount

The initial amount is when a=0

P = 0.99987⁰ = 1

The Pressure at Sea Level=1

II. Decay factor

This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.

III. Decay Rate = 1-0.99987 = 0.00013

Expressed in Percentage = 0.013%

Find the volume of a right circular cone that has a height of 18.9 in and a base with a
Dmitriy789 [7]

Answer:

The volume of the cone is:

  • <u>112.6 cubic inches.</u>

Step-by-step explanation:

You should know that the volume of a straight circular cone is equal to:

  • Cone volume = (1/3) PI * r ^ 2 * h

Where:

<em>r = radius. </em>

<em>h = height. </em>

Since the radius and diameter are not provided in the exercise but the circumference, the circumference formula should be used and the diameter must be cleared:

  • Circumference = PI * Diameter.

When clearing you get:

  • Diameter = circumference / PI

By replacing the data you get:

  • Diameter = 15 inches / PI
  • Diameter = 4.77 inches.

Since the radius is equal to half the diameter, then the diameter is equal to 2,385 inches, now having the value of radius we proceed to replace in the volume formula:

  • Cone volume = (1/3) PI * 2.385 in^2 * 18.9 in
  • Cone volume = 112.581541 in^3
  • <u>Cone volume = 112.6 in^3</u>
