Well $25 is the standard price initially.

$10 is added every hour as a constant rate.

Sphere A has a diameter of 2 and is dilated by a scale factor of 3 to create sphere B. What is the ratio of the volume of sphere

krok68 [10]

Answer:

1:27 (D)

Step-by-step explanation:

Given:

Sphere A has a diameter of 2

Sphere A is dilated to create sphere B

Scale factor = 3

Volume of a sphere = 4/3 πr³

Radius = r = diameter/2 = 2/2

r = 1

Volume of sphere A = 4/3 ×π(1)³

Volume of sphere A = 4/3 × π

Volume of sphere B = 4/3 πR³

Since the diameter was dilated, the diameter of B = diameter of A × scale factor

diameter of B = 2×3 = 6

Radius of B = R = diameter/2 = 3

Volume of sphere B = 4/3 × π(3)³

Volume of sphere B = (4/3)(27)π

Ratio of the volume of sphere A to volume of sphere B

= [4/3 ×π]: [(4/3)(27)π]

= (4π/3)/[(4π/3)×27] = 1/27

= 1:27

Describe the steps you would take to solve the given literal equation for m as shown.

solniwko [45]

T = 2 $\pi$ $\sqrt{m/k}$

1. Divide both sides by 2 $\pi$
--> t / 2 $\pi$ = $\sqrt{m/k}$

2. Square both sides
--> $t^{2}$ / 4 $\pi^{2}$ = m / k

3. Multiply both sides by k
--> m = k $t^{2}$ / 4 $\pi ^{2}$
