Answer:

1/8 + 1/2 = 5/8

Step-by-step explanation:

Total number of beads = 8

Number of green beads = 4

Number of yellow beads = 1

Fraction of green beads :

Number of green / total number of bead = 4 / 8 = 1/2

Fraction of yellow beads :

Number of yellow / total number of bead = 1 / 8

Number of green or yellow bead :

1/8 + 1/2 = (1 + 4) / 8 = 5/8

What is the total surface area of the code?
Ksju [112]
<h2>Hello!</h2>

The answer is: None of the options.

The correct answer is: 703.69cm^{2}

<h2>Why?</h2>

The total surface area of the cone is equal to:

TotalArea=BaseArea+LateralArea

Calculations:

tex]BaseArea=\pi*r^{2}=\pi*7^{2}=153.94cm^{2}[/tex]

LateralArea=BasePerimeter*SlantHeight/2\\BasePerimeter=2*\pi*r=2*\pi*7=43.98cm\\SlantHeight=\sqrt{height^{2}+radius^{2}  }=\sqrt{576+49}=\sqrt{625}=25

[LateralArea=43.98*\frac{25}{2}=549.75cm^{2}

So,

TotalArea=153.94cm^{2} +549.75cm^{2}=703.69cm^{2}

Have a nice day!
