Let  First Sphere be the Original Sphere

its Radius be : r

We know that Surface Area of the Sphere is : 4π × (radius)²

⇒ Surface Area of the Original Sphere = 4πr²

Given : The Radius of Original Sphere is Doubled

Let the Sphere whose Radius is Doubled be New Sphere

⇒ Surface of the New Sphere = 4π × (2r)² = 4π × 4 × r²

But we know that : 4πr² is the Surface Area of Original Sphere

⇒ Surface of the New Sphere =  4 × Original Sphere

⇒ If the Radius the Sphere is Doubled, the Surface Area would be enlarged by factor : 4

The 30/60/90 right triangle is the biggest cliche in trig.  We recall the sides come in ratio 1:\sqrt{3}:2

1:\sqrt{3}:2 = x:y:4\sqrt{2}

First x:

\dfrac x 1 = \dfrac{4 \sqrt{2}}{2}

x = 2 \sqrt 2

Next y:

\dfrac{y}{\sqrt{3}} =\dfrac{x}{1}

y= 2 \sqrt{2} \sqrt{3} = 2 \sqrt{6}

Choice C

Answer:

x = <u>12/5</u>

Step-by-step explanation:

Since the original is 10 and the second is 6, that means that the scale is 10:6 or 5:3.  It can also be related as %60 of the length.

<u>Step 1:  Make an equation</u>

10/6 = 4/x

<u>Step 2:  Cross Multiply</u>

10x = 24

<u>Step 3:  Divide</u>

10x / 10 = 24 / 10

24/10 = 12/5

x = 2.4
