3. Luis wants to calculate the volume of his globe. The globe is in the shape of a sphere, as represented in
Aloiza [94]

The measure which is closest to the volume of Luis's globe is; 6301.2in³

<h3>Volume of a sphere</h3>

If the circumference of the globe along the equator is 72inches along the equator;

  • C = 72 = 2π× r

Hence, the radius of the globe can be evaluated as;

  • r = 72/(2×3.14)

  • r = 72/6.28

r = 11.46in.

On this note, the Volume, V of the globe is;

  • V = (4/3) × π × r³

  • V = (4/3) × 3.14 × 11.46³

V = 6301.2in³

NEED HELP ASAPInstructions: Find the length of the missing sides. Round your answers to the
Pie

Answer:

x = 9.4

y = 17.7

Step-by-step explanation:

Given: The figure

Required: Find x and y

The relationship between length x, length 15 and angle 32 is as follows:

tan \theta = \frac{opp}{adj}

So, we have:

tan\ 32= \frac{x}{15}

Cross multiply:

x =15*tan\ 32

x = 15 * 0.6248693519

x = 9.3730402785

x = 9.4 --- approximated

Similarly:

The relationship between length y, length 15 and angle 32 is as follows:

cos \theta = \frac{adj}{hyp}

So, we have:

cos\ 32= \frac{15}{y}

Cross Multiply:

y * cos\ 32= 15

Solve for y

y = \frac{15}{cos\ 32}

y = \frac{15}{0.84804809615}

y = 17.6876760506

y = 17.7 --- approximated

Please can someone help me on these? solve this equation by factorising: 2x^2 + 5x + 2 = 0
slavikrds [6]
2x^2 + 5x + 2 = 0\\&#10;2x^2+4x+x+2=0\\&#10;2x(x+2)+1(x+2)=0\\&#10;(2x+1)(x+2)=0\\&#10;x=-\frac{1}{2} \vee x=-2

x^2-4x+1=0\\&#10;x^2-4x+4-3=0\\&#10;(x-2)^2=3\\&#10;x-2 =\sqrt3 \vee x-2=-\sqrt3\\&#10;x=2+\sqrt3 \vee x=2-\sqrt3

Which of the following is the number of sides for a regular polygon that will not form a regular tessellation?
trasher [3.6K]

Answer with explanation:

A regular polygon is simple closed geometrical shape, only made up of line segments.

And Regular Tessellation, is geometrical shape, made up of regular polygons having, 3 ,or 4 or 6 sides.

It is combination of, only single kind of polygon,either, polygon having 3 sides, or ,4 sides or 6 sides.

→Regular polygon having 3 sides is Called Equilateral Triangle.

→Regular polygon having 4 sides is Called Square.

→Regular polygon having 6 sides is Called Regular Hexagon.

⇒Regular polygon having , 8 sides will not form a regular tessellation.
