Answer:

The volume of a cylinder is found by multiplying the area of its top or base by its height and is defined as: V = π· r2· h

Thus: V≈15927.87 in³

how to find the area of each circle. use a calculator value of pi. round the answer to the nearest tenth

tankabanditka [31]

Answer:

A = 201.0 mi^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know that r = 8

A = (3.14) *8^2

A = 3.14 * 64

A = 200.96 mi ^2

Rounding to the nearest tenth

A = 201.0 mi^2

In the band there are twice as many tubas as French horns and three more trumpets than tubas. Five times the number of trumpets

GenaCL600 [577]

Answer:

3 French horns

6 tubas

9 trumpets

Step-by-step explanation:

Let the number of French horns be x.

Number of French horns = x

There are twice as many tubas as French horns, so

Number of tubas = 2x

There are three more trumpets than tubas, so

Number of trumpets = 2x + 3

Five times the number of trumpets equals nine times the number of French horns, plus triple the number of tubas, so

$5(2x+3)=9x+3\cdot 2x\\ \\10x+15=9x+6x\\ \\10x+15=15x\\ \\15=15x-10x\\ \\15=5x\\ \\x=3\\ \\2x=6\\ \\2x+3=6+3=9$

Simplify. Rewrite the expression in the form y^ny n y, start superscript, n, end superscript. y^{-4}\cdot y^{3}=y −4 ⋅y 3 =y, st

inn [45]

Answer:

$y^{-4}\cdot y^3=y^{-1}$ .

Step-by-step explanation:

The given expression is

$y^{-4}\cdot y^3$

We have to simplify the above expression. in form of $y^n$ .

Using property of exponents, we get

$y^{-4}\cdot y^3=y^{-4+3}$ $[\because a^ma^n=a^{m+n}]$

After addition of exponents, we get

$y^{-4}\cdot y^3=y^{-1}$

Therefore, $y^{-4}\cdot y^3=y^{-1}$ .
