1 answer:

3 0

----------------------------------------
Formula:
----------------------------------------
Volume of a cylindrical pipe = πr²h

----------------------------------------
Find Radius:
----------------------------------------
Radius = Diameter ÷ 2
Radius = 4 ÷ 2
Radius = 2 in

----------------------------------------
Find Volume of the pipe:
----------------------------------------
Volume of a cylindrical pipe = π x 2² x 6

Volume of a cylindrical pipe = 24π

Volume of a cylindrical pipe = 75.40 in³ (nearest hundredth)

----------------------------------------
Answer: 75.40 in³

Answer:

$- 30$

Step-by-step explanation:

$\sin {}^{ - 1} ( - \frac{1}{2} ) =$

Using the identity,

$\sin( - x) = - ( \sin(x) )$

$\sin( \frac{1}{2} ) = \frac{\pi}{6}$

$\sin {}^{ - 1} ( \frac{ - 1}{2} ) = - \frac{\pi}{6}$

Convert to degrees.

Answer:

The area is 243 square feet

Step-by-step explanation:

The perimeter of a rectangle is the sum of all four sides.

Two of the sides represent the length and two represent the width.

Given what we know and using l to represent the length and w to represent the width.

l + l + w + w = 72ft

or more concisely

2l + 2w = 72ft

The four sides all add together to equal 72ft

We also know that

l = 3w

This says the length is equal to 3 times the width

we have two unknowns, l and w, and now we have two related equations so we can solve for l and w.

The first thing we will do is replace l with 3w in the first equation because the second equation tells us that l is the same as 3w. Making the replacement gives us

2(3w) + 2w = 72ft

2 times 3w is 6w

6w + 2w = 72ft

6w plus 2w is 8w

8w = 72ft

Now if we divide both sides by 8 we maintain the equality since we are making the same change to both sides

8w / 8 = 72ft / 8

8w divided by 8 is 1w or just w and 72ft divided by 8 is 9ft

w = 9ft

So now we know the width is 9ft

if we now replace w with 9 in one of our original equations we can solve for l, let's use l = 3w

l = 3(9ft)

3 times 9 is 27 so

l = 27ft

So the length is 27ft which is 3 times the width of 9ft

The area of a rectangle is length times width or l x w, so

area = 27ft x 9ft

area = 243sqft

ft means feet and sqft means square feet

Miguel deposits $5000 in an account

jeyben [28]

Then the amount of money will he have in his account after 10 years will be $7,454.16. Then the correct option is B.

<h3>What is compound interest?</h3>

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

Miguel deposits $5000 in an account earning 4% interest compounded monthly.

Then the amount of money will he have in his account after 10 years will be

We know the compound interest formula.

$A = P (1 + r)^t$

Where

A = amount

P = principal

r = rate of interest

t = time period (in year)

Then we have

$\rm A = 5000 (1 + 0.04)^{10}\\\\A = 5000 (1.04)^{10}\\\\A = \$ \ 7454.16$
