The exact volume of the cylinder is 32,169.91 in. cb.

V=(pi)r^2h
V=(pi)16^2(40)
V=(pi)256(40)
V=10,240(pi)
V=32,169.91

Hope this helps! :)

Well in order to get the answer first, you would the heighth (40) and multiply it by the radius (16) so.....
40 x 16= 640 then
.... V= 640 That is how you find the volume

X-y=-3<br> Anyone know how to do this ?

horsena [70]

X - y = -3

Move constant to the left by adding its opposite to both sides

x - y + 3 = -3 + 3

The sum of two opposites equals

your answer would be: x - y + 3 = 0

Alicia walks 4 miles in 1 hour and can speed walk 5 miles in 1 hour. What percent of Alicia's average speed walking rate is her

RSB [31]

Answer:

The % Alicia speed walking is 125 % of average walking

Step-by-step explanation:

Given as :

Distance cover by Alicia while walking = 4 miles

Time taken = 1 hour

So, Speed of Alicia while walking = $\frac{Distance}{Time}$

Or, S 1 = $\frac{4 miles}{1 hour}$

I.e S 1 = 4 mph

And

Distance cover by Alicia while speed walk = 5 miles

Time Taken = 1 hour

So, Speed of Alicia while speed walking = $\frac{Distance}{Time}$

Or, S 2 = $\frac{5 miles}{1 hour}$

I.e S 2 = 5 mph

Or, % Rate = $\frac{5}{4}$ ×100 = 125

Hence The % Alicia speed walking is 125 % of average walking Answer

What would be the difference at the end of one year between the simple interest earned on a deposit of $450 at 4.5% and the comp

Len [333]

Answer: $0

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 1 year

P = $450

R = 4.5%

Therefore

I = (450 × 4.5 × 1)/100

I = 2025/100

I = 20.25

For compound interest,

Initial amount deposited into the account is $450 This means that the principal,

P = 450

It was compounded annually. This means that it was compounded once in a year. So

n = 1

The rate at which the principal was compounded is 4.5%. So

r = 4.5/100 = 0.045

It was compounded for just a year. So

t = 1

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. Therefore

A = 450 (1+0.045/1)^1×1

A = 450(1.045) = $470.25

Compound interest = 470.25 - 450 = 20.25

The difference is 20.25 - 20.25 = 0
