Answer:

328 square inches

PLZ MARK AS BRAINLIEST

Step-by-step explanation:

Lateral Area of Pyramid:

L = 1/2P<em>l</em>

<em>l</em> = 15.9

P = 2(8.2) + 2(8.2) = 32.8

L = 1/2(32.8)(15.9) = 260.76

Surface Area:

SA = B + L

B = (8.2)(8.2) = 67.24

L = 1/2(32.8)(15.9) = 260.76

SA = 67.24 + 260.76 = 328

A surveyor measures the angle of elevation to a point on a mountain to be 12 degrees. The point on the mountain is horizontally
olchik [2.2K]
From the right triangle formed, the adjacent side to the angle of elevation is 5 miles and the vertical change in elevation is the opposite side. From the trigonometric function, tangent of an angle,
                             tan 12° = x / 5 miles
The value of x from the equation is 1.06 miles. Thus, the vertical change in elevation is 1.06 miles.

What is the ratio of the volumes of a cylinder and a cone having the same base radius and height
asambeis [7]

The ratio of the volumes of a cylinder and a cone having the same base radius and height is 3 : 1

<u>Solution:</u>

Given that, we have to find What is the ratio of the volumes of a cylinder and a cone having the same base radius and height.

Let "r" be the radius and "h" be the height of cylinder and cone

Let us calculate the volume of cylinder and cone

<em><u>The volume of cylinder is given as:</u></em>

\text { Volume of a cylinder }=\pi r^{2} h

where "r" is the radius and "h" is the height of cylinder

<em><u>The volume of cone is given as:</u></em>

\text { volume of a cone }=\frac{1}{3} \pi r^{2} h

Now, <em>ratio of volumes = volume of cylinder : volume of cone</em>

\text { Ratio of volumes }=\pi r^{2} h: \frac{1}{3} \pi r^{2} h

Cancelling the common terms on both sides, we get,

\text { Ratio of volumes }=1: \frac{1}{3}

By multiplying with 3, we get

Ratio of volumes = 3 : 1

Hence the ratio of volume of cylinder to cone is 3 : 1
