A silo is shaped like a cylinder with a cone on top. The radii of the bases of the cylinder and cone are both equal to 8 feet. T
dangina [55]
Answer: 6702.1

Explanation:
Volume of cylinder = πr^2h
= π(8^2)25
= 1600 π

Volume of cone = πr^2(h/3)
= π(8^2)(25/3)
= π (64)(25/3)
= (1600 π)/3

Add these two numbers
= 1600 π + (1600 π)/3
= (4800 π+ 1600 π)/3
= 6400 π/ 3
=6702.06≈6702.1

Find the image of A(6, -4) after it is reflected over the line y = - 2, then reflected over the line x = 1. (-4, 6) (-4, 0) (-4,
olchik [2.2K]

Answer:(-4,0)

Step-by-step explanation:

Given

Point A (6,-4)

Reflection of Point A about line y=-2 is

A' (6,0)

If any Point is reflected about any line y=constant then its x coordinate remains same

Now reflection of Point A' about x=1 is

A'' (-4,0)

If any point  is reflected about line x=constant then its y coordinate remains same

Figure I and Figure II are similar figures,
ELEN [110]

The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,

\frac{ST}{EF}=\frac{WR}{CD}

Thus the option H is the correct option.

To find the correct proportion we need to know about the properties of slimier polygon.

<h3>What are the properties of similar polygon?</h3>

Two polygons are said to be similar or congruent pentagon-

The corresponding angle of two pentagons are congruent.

The ratio of corresponding sides is same for all the sides.

The figure given in the problem of similar two polygons with six sides.

Rearrange the second figure as shown in figure.

As for the similar polygons, the ratio of corresponding sides is same for all the sides.

Thus the sides shown in the two rearranged figure must be same. Therefore,

\frac{ST}{EF}=\frac{WR}{CD}

Hence the correct proportion is,

\frac{ST}{EF}=\frac{WR}{CD}

Thus the option H is the correct option.

The area of the right triangle = \frac{1}{2}bh

b = base = SV = 12.3
h = hight = HL = 24.6
A = area
\frac{1}{2}bh = A
\frac{1}{2}(12.3)(24.6) = 151.29
