Identify the surface area of the composite figure in terms of π.

Mathematics
1 answer:
Katena32 [7]3 years ago
7 0

Answer:

  78π m²

Step-by-step explanation:

The lateral area of the cylinder is ...

  LA = 2πrh

  LA = 2π(3 m)(8 m) = 48π m²

The lateral area of one cone is ...

  LA = πrh . . . . where h is the slant height

  LA = π(3 m)(5 m) = 15π m²

Then the total surface area of the figure is the area of the two cones plus that of the cylinder:

  S = 2(cone area) + cylinder area

  S = 2(15π m²) +(48π m²)

  S = 78π m²

A certain book is for sale in both Belize and Brazil. In Belize, it sells for 80.39 Belize dollars. In Brazil, it sells for 63.6
kompoz [17]
A book is sold in Belize for 80.39 Belize dollars.
In Brazil, it sells for 63.65 Brazilian reals.

The exchange rate of US Dollars to Belize Dollars is 1:1.9246
<span>The exchange rate of US Dollars to Brazilian Real is 1:1.7880
</span>
If we convert the two into dollars,
Belize Dollars 
1 : 1.9246 = X : <span>80.39 
1.9246X = 80.39
X = $ 41.77 

</span>Brazilian Real
1 : 1.7880 = X : 63.65 <span> 
</span>1.7880X = 63.65 <span>
X = $ 35.60
</span>
Difference = $ 41.77 - $ 35.60
Difference = $ 6.17

<span>So, in Belize the book is more expensive by $ 6.17</span>

Write the slope-intercept form of the equation of the line.
Semenov [28]

Answer:

y = x + 2

Step-by-step explanation:

First, find the slope.

(y2 - y1 / x2 - x1)

I'm going to use (0,-2) and (2,0) as my points.

Find the slope.

(-2) - 0 / 0 - 2= -2 / -2 = 1

So the slope is 1.

Now find the y-intercept.

Y-intercept is 2.

Now substitute it into the slope-intercept form equation. (y = mx + b)

y = x + 2
