Answer:

44580 inches

Step-by-step explanation:

Given, D (diameter)= 22 inches

Therefore, r (radius)= 22/2= 11 inches

Volume= $\frac{4}{3}$ ×π×r³

= $\frac{4}{3}$ ×3.14×22×22×22

=44579.626 inches

What is the difference between dash and hyphen

UNO [17]

Hyphens and Dashes. A hyphen joins two or more words together while a dash separates words into parenthetical statements. The two are sometimes confused because they look so similar, but their usage is different. Hyphens are not separated by spaces, while a dash has a space on either side.

Help me with these math questions........ WITH SCREENIES

Nutka1998 [239]

Answer: 6.3093

Step-by-step explanation:

$3^{\frac{x}{5}} = 4$

$ln3^{\frac{x}{5}} = ln4$

$\frac{x}{5} ln3 = ln4$

xln3 = 5ln4

$x = \frac{5ln4}{ln3}$

x = 6.3093

Answer: 5, 3, $\frac{1}{5}$ , D

Step-by-step explanation:

a) x ≤ 0 so, f(-5) = | -5 | = 5

x ≤ 0 so, f(-3) = | -3 | = 3

x > 0 so, f(5) = $\frac{1}{5}$

b) graph D

Answer: $\frac{\pi}{12}$

Step-by-step explanation:

$\frac{25\pi}{12} - \frac{2\pi}{}$

Why is it helpful to write numbers in different ways

Goshia [24]

You should write numbers in as many ways as you possibly can to make new connections in your brain. Knowing how to write numbers in many different ways can help you solve complex problems more easily. Doing this can also reinforce the mathematical principles and logic you have memorised.

Writing one in many different ways:

1=1/1=2/2=3/3=4/4=(-1)/(-1)=(-2)/(-2)

=1.0=1.00=1.000=(1/2)+(1/2)=(1/3)+(1/3)+(1/3)

=(1/4)+(1/4)+(1/4)+(1/4)

Writing a half in many different ways:

1/2=(1/4)+(1/4)=(1/6)+(1/6)+(1/6)

=(1/8)+(1/8)+(1/8)+(1/8)=4*(1/8)

=2/4=3/6=4/8=5/10=0.5=0.50

etc...etc...

Which quadratic equation is equivalent to (x + 2)^2 + 5(x + 2) - 6 = 0?

Ber [7]

Answer:

$x^2$ + 9x + 8 = 0

Step-by-step explanation:

First, we have to simplify this quadratic equation:

(x+2)^2 + 5(x+2) - 6 = 0

x^2 + 4x + 4 + 5x + 10 - 6 = 0

x^2 + 9x + 8 = 0
