Answer:

4445.18 pulgadas cúbicas

Step-by-step explanation:

Paso 1

La fórmula para la circunferencia de una esfera = 2πr

Circunferencia de una esfera = 64 pulgadas

Por eso,

64 = 2πr

Por lo tanto, encontramos r

Dividir ambos lados por 2π

64 / 2π = 2πr / 2π

r = 10.185916358 pulgadas

Radio r = 10.2 pulgadas

Paso 2

Volumen de una esfera

= 4/3 × π × r³

r = 10.2 pulgadas

Por lo tanto, 4/3 × π × (10.2) ³

= 4445.18 pulgadas cúbicas

Por lo tanto, el volumen en pulgadas cúbicas de una esfera = 4445.18 pulgadas cúbicas

Given a point A(-3,-1), it is dilated by some scale

Sidana [21]

Answer:

$B' = (-3, -15)$

Step-by-step explanation:

Given

$A = (-3,-1)$

$A' = (-9,-3)$

$B = (-1,-5)$

Required

Determine the coordinates of B'

Since A' is the image of A; we need to first calculate the scale factor using

$A' = A * Scale\ factor$

Make Scale Factor the subject

$Scale\ Factor = \frac{A'}{A}$

Substitute values for A' and A

$Scale\ Factor = \frac{(-9,-3)}{(-3, -1)}$

Factorize the numerator

$Scale\ Factor = \frac{3 * (-3,-1)}{(-3, -1)}$

$Scale\ Factor = \frac{3 * 1}{1}$

$Scale\ Factor = 3$

The coordinates of B' is then calculated as follows:

$B' = B * Scale\ Factor$

Substitute values for B and Scale Factor

$B' = (-1,-5) * 3$

$B' = (-3, -15)$

andreyandreev [35.5K]

Look at the picture.

x is the distance between Mary and Jan.

Using the Pythagorean theorem:
$x^2=10^2+24^2 \\
x^2=100+576 \\
x^2=676 \\
x=\sqrt{676} \\
x=26$

The distance between Mary and Jan is 26 miles.
