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

Help picture below problem 16
weeeeeb [17]

The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.

     *<em>look at the image I attached for a better explanation</em>

By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation

    ?^2+9^2 = 16^2\\?^2 + 81=256\\?^2 = 175\\? = 13.2

Thus the <u>missing side length is 13.2 cm</u>

Hope that helps!

Someone explain!! geometry
ikadub [295]

Step-by-step explanation:

sin 0 = opposite ÷ hypothenus

sin 0 = 3 / 5

3 / 5 = x / 15

5 × n = 15

n = 3

x = 3 × 3 = 9

y = use pythagoras

= 12

tan 0 = opposite ÷ adjacent

tan 0 = 9/12

Marco is making a kite, using sticks for its diagonals. One stick is 2 feet long and the other is 3 feet long. How much material
Marat540 [252]

Answer:

Marco will need 3\ ft^{2} of material to make the kite

Step-by-step explanation:

we know that

To know how much material Marco will need to make the kite, the area must be calculated.

Remember that the area of the kite is equal to

A=\frac{1}{2}[d1*d2]

where

d1 and d2 are the diagonals of the kite

we have

d1=2\ ft

d2=3\ ft

substitute

A=\frac{1}{2}[2*3]=3\ ft^{2}
