What is the surface area of the cone? (Use 3.14 for π.)

aev [14]

Answer: 117.226666667 cm^3

Step-by-step explanation:

So, we all know the formula for working out the volume of a cone is

V= 1/3πr^2h

V = 1÷3 x 3.14 × r^2 x h

The radius is half the diameter. Your diameter is 8 so the radius would be 4. And 7 is your height by the way.

So let's plot it all in!

V= 1÷3 x 3.14 × 4^2 x 7

V = 117.226666667cm^3

Round to the nearest 10 = 117.2cm^3

To the nearest 100 = 117.23cm^3

To the nearest whole number = 117cm^3

Answer:

UCL (x bar) = 424

LCL (x bar) = 376

Step-by-step explanation:

Given:

Average calories contained, μ = 400

Standard deviation, σ = 30 calories

Sample size, n = 25

a) UCL (x bar) = $\mu+\frac{4\sigma}{\sqrt{n}}$

On substituting the respective values, we get

UCL (x bar) = $400+\frac{4\times30}{\sqrt{25}}$

UCL (x bar) = 424

Similarly,

LCL (x bar) = $\mu-\frac{4\sigma}{\sqrt{n}}$

On substituting the respective values, we get

LCL (x bar) = $400-\frac{4\times30}{\sqrt{25}}$

LCL (x bar) = 376

Ms. Watts is a famous motivational speaker. She travels across the country by jet and gives an average of ten presentations a we

expeople1 [14]

Answer:

5 weeks

Step-by-step explanation:

We are told that the auditorium holds an average of 1000 people each.

And that she charges $40 each.

Thus;

Total income for each speech is;

1000 × 40 = $40000

Since she gives an average of 10 presentations each week.

Total income per week = 10 × 40000 = $400,000

Now,the expenses she makes for each speech weekly is;

Renting auditorium = $15000

Motel, jet expenses, support personnel = $75000

Thus,

Total expenses per week = 15000 + 75000 = $90000

Now, total profit per week is;

P_weekly = Total income per week - Total expenses per week

P_weekly = $400000 - $90000

P_weekly = $310000

There are 52 weeks in a year, thus, profit in a year is;

P_yearly = 52 × 310000 = $16120000

Now, we want to find out how long it took her to make $1,400,000 a year.

We know that;

$16120000 was achieved in 52 weeks

Thus;$1,400,000 will be achieved in;

(1400000 × 52)/16120000 = 4.52 weeks approximately 5 weeks.
