Find the volume of the solid where the cone and half sphere are hollow. Use 3.14 for П ; height is 19 in; radius is 5 in. Round

Vera_Pavlovna [14]

Volume of Solids

The volume of the solid is 758.83 in³

Step-by-step explanation:

Given that the cone and half sphere is hollow

The volume of the cone = $1/3 \pi r^{2} h\\$

The Volume of the sphere = $4/3 \pi r^{3}$

So the Volume of the half sphere = $2/3\pi r^{3}$

The volume of solid = volume of cone + volume of the half sphere

$V = V_{1} + V_{2}$

Given

height h = 19 in

radius r = 5 in

$V_{1\\}$ = $1/3 \pi r^{2} h$

= 1/3 × 3.14 × 5 × 5 × 19

= 497.16 in³

$V_{2} = 2/3 \pi r^{3}$

= 2/3 × 3.14 × 5 × 5 × 5

= 261.67 in³

V = 497.16 in³ + 261.67 in³

= 758.83 in³

Hence the volume of the solid is 758.83 in³

A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6

ddd [48]

Answer:

The population of bacteria after 6 days is 2,313.06

Step-by-step explanation:

Given as :

The initial population of bacteria = i = 1,000 bacteria

The growth rate of bacteria per day = 15%

Let The population of bacteria after 6 days = f

The time period of growth = 6 days

Now, According to question

The population of bacteria after 6 days = initial population × $(1+\dfrac{\textrm rate}{100})^{\textrm time}$

Or, f = i × $(1+\dfrac{\textrm r}{100})^{\textrm t}$

Or, f = 1000 × $(1+\dfrac{\textrm 15}{100})^{\textrm 6}$

Or, f = 1000 × $(1.15)^{6}$

Or, f = 1000 × 2.31306

∴ f = 2,313.06

So,The population of bacteria after 6 days = f = 2,313.06

Hence,The population of bacteria after 6 days is 2,313.06 Answer
