22cm^3

Step-by-step explanation:

My education system is different so I dont know what nearest tenth would mean in this .

But going mathematically:

Its diameter is 7 centimetres.

So to find its volume we can use the formula pi/d or pi/r^2

Now, 22/7÷7 would be 22cm³.

Answer:

Step-by-step explanation:

1. ¹/₃ × π × r² × l:so 33.9.29cm³

2. π × r² × l:so π x 2² x 3.5=43.98ft³

3.¹/₃ × π × r² × l, to get the radius from diameter you divide the diameter by 2 so it would look like: ¹/₃ × π x 4² x 12= 201.06in³

4.352cm³

5. cone: 1/3 πr²h

Cylinder: πr²h

cone : 33 Cylinder = 3 x 33 = 99 in³

the length of a rectangle is 4 meters longer than the width. if the area is 22 square meters , find the rectangle dimension

Readme [11.4K]

Let breadth be x

Length=x+4

We know

$\boxed{\sf Area_{(Rectangle)}=Length\times Breadth}$

$\\ \sf\longmapsto x(x+4)=22$

$\\ \sf\longmapsto x^2+4x=22$

$\\ \sf\longmapsto x^2+4x-22=0$

By solving

$\\ \sf\longmapsto x=-2\pm\sqrt{26}$

Given that n^2/3 = 8 and n> 0

nalin [4]

Answer:

16 $\sqrt{2}$

Step-by-step explanation:

Using the rule of exponents/ radicals

$a^{\frac{m}{n} }$ = $\sqrt[n]{a^{m} }$ , then

$n^{\frac{2}{3} }$ = $\sqrt[3]{n^2}$ , then

$\sqrt[3]{n^2}$ = 8 ( cube both sides )

n² = 8³ ( take the square root of both sides )

n = $\sqrt{8^3}$

= $\sqrt{512}$

= $\sqrt{256(2)}$

= $\sqrt{256}$ × $\sqrt{2}$

= 16 $\sqrt{2}$
