Calculate the missing length for this cylinder

Mathematics
2 answers:
QveST [7]3 years ago

For first cylinder Vloume = pi * r^2 * h 
where h is the height and r is the radius 
so by substitute
6908=pi * r^2 * 22
so r = 9.99 cm
For second cylinder Vloume<span> = pi * r^2 * h 
by substitute  
7884.54 = pi * r^2 * 31
so r = 8.99 
but the diameter is the required so 
d= 2*r = 2*8.99 
d= 17.99 cm</span>

I assume by the length you mean height so,

\frac{6908}{ \pi * 22^{2} } ≈ <span>4.54.

if you're supposed to round it, it'd be either 4.50, or 5

I hope this helps

If the store currently charges a price of $50, then increases that price to $60, what happens to total revenue from shoe sales (
Goryan [66]

Answer:

<h2>Revenue will decrease</h2>

Step-by-step explanation:

Note: the question did not provide the quantity to work with, so we will assume some values, say quantity Q= 30

Generally, it is normal for the revenue to decrease when the price of a commodity increase, this is so that buyer will have to react to adjust to the change in price.

When price increase from $50 to $60, the total revenue will decrease

let say the quantity Q1=30 , and the new quantity after price increase is Q2=20

1. The revenue PxQ before price change will be

PxQ= P1xQ1=50*30

PxQ= $1500

1. The revenue PxQ after price change will be

PxQ=P2xQ2= 60*20

P2xQ2= $1200

This clearly shows that based on the assumed data, the total revenue will drop from1500 to 1200, a total of $300 in a decrease

Is 1.2 less than or higher than 1.5
Olenka [21]

1.2 is less than 1.5

If you cancel out 1 from both numbers you're left with .2 and .5

Multiply both by 10 and get 2 and 5.

Obviously 2 is less than 5.

A house that costs $125,400 appreciates at a rate of 3% each year. What is the value of the
ser-zykov [4K]

Answer:

The value after three years is $137,027.97

Step-by-step explanation:

Here, we want to get the value of the home after 3 years

Generally, we have the exponential formula as follows;

y = P(1 + r)^t

where P is the original cost which is $124,400

r is the rate of increase which is 3% = 3/100 = 0.03

t is the time which is 3 years

Substituting these values;

y = 125400(1 + 0.03)^3 = $137,027.97
