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!

Use a graphing calculator to solve the equation -3 cost= 1 in the interval from . Round to the nearest hundredth.
RSB [31]
In place of t, or theta, I'm going to utilize x instead. So the equation is -3*cos(x) = 1. Get everything to one side and we have -3*cos(x)-1 = 0

Let f(x) = -3*cos(x)-1. The goal is to find the root of f(x) in the interval [0, 2pi]

I'm using the program GeoGebra to get the task done of finding the roots. In this case, there are 2 roots and they are marked by the points A and B in the attachment shown

A = (1.91, 0)
B = (4.37, 0)

So the two solutions for theta are
theta = 1.91 radians
theta = 4.37 radians

I want to cover the curved surface of a cylinder with orange paper. My cylinder is 14” tall. The diameter is 3.5”. I have listed
Dominik [7]
Circumference of the cylinder = 3.14 x 3.5 = 10.99 = 11 inches
 so D. 11 x 14 is correct for the first part

area of the top  =  PI x r^2 = 3.14 x 1.75^2 = 9.62 inches

top and bottom = 9.62 x 2 = 19.23 = A. 19 inches
