Answer:

<h2> 8in</h2>

Step-by-step explanation:

the given formula in the question is not correct

here is the correct formula

S. A. =2πr^2 +2πrh

given that S.A=207.24

radius r= 3in

207.24=2*3.142*(3)^2 +2*3.142*(3)h

207.24=56.556 +18.852h

207.24-56.556=18.852h

150.684=18.852h

h=150.684/18.852

h=7.99

Approximately the height is 8in

What percentage of 340 is 425?
beks73 [17]

Answer:

125%

Step-by-step explanation:

1. Set up the equation

425/340 = x/100

(percentages are out of 100 so this equation means 425 out of 340 is equal to a number out of 100)

2. Cross multiply

340x = 42500

3. Solve for x

x = 125

Which expressions below are equivalent to
Yuri [45]

Answer:

<h2>A, B, D, E</h2>

Step-by-step explanation:

2(2x + 1) = (2)(2x) + (2)(1) = 4x + 2 → A

<em>used distributive property</em>

2(2x + 1) = 2(1 + 2x) → B

<em>used commutative property</em>

2(2x + 1) = (2x + 1) + (2x + 1) = 2x + 1 + 2x + 1 → D

<em>used 2a = a + a</em>

2(2x + 1) = 4x + 2 = x + x + x + x + 1 + 1 → E

<em>used 4x = x + x + x + x and 2 = 1 + 1</em>

Identity the construction that the figure represents
nordsb [41]

The construction is the construction of the Perpendicular bisector.

<h3>How to illustrate the information?</h3>

The steps for the construction of perpendicular bisectors are as follows:

Open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.

Call the two points where these two arcs meet X and Y. Draw the line between X and Y.

So, the point where this line meets the line segment; M is called the mid point and the line XY is the perpendicular bisector of the line AB.

The figure is a construction of perpendicular bisector.
