Answer:

(25\pi\ -24)\ cm^{2}

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the circle minus the area of the two isosceles triangles

so

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

where r is the radius of the circle

In this problem we have

r=5\ cm

substitute

A=\pi (5)^{2}

A1=25\pi\ cm^{2}

Find the area of the two triangles

The area of the two isosceles triangles is equal to

A=2[\frac{1}{2}bh]=bh

we have

b=6\ cm

h=5-1=4\ cm

substitute

A2=6*4=24\ cm^{2}

Find the area of the shaded region

A1-A2=(25\pi\ -24)\ cm^{2}

The value of the surface area of the cylinder is equal to the value of the volume of the cylinder. Find the value of x.
zlopas [31]

Answer:

x = 2.5

Step-by-step explanation:

Surface area of cylinder = 2πr(h + r)

Volume of cylinder = πr²h

Given that S.A = Volume of the cylinder, therefore, we have:

2πr(h + r) = πr²h

Radius (r) is given as 2.5 cm

height (h) = x cm

Input the values and solve for x

2πr(h + r) = πr²h

2πr(h + r) = πr(rh)

2(h + r) = rh (πr cancels πr)

2(x + 2.5) = 2.5*x

2x + 5 = 2.5x

Subtract 2x from both sides

2x + 5 - 2x = 2.5x - 2x

5 = 0.5x

Divide both sides by 0.5

\frac{5}{0.5} = \frac{0.5x}{0.5}

2.5 = x

x = 2.5

How was pre-image ABC transformed to create image AꞌBꞌCꞌ? A. 90° clockwise rotation around point C B. reflection over segment BC
slava [35]
<span>There are 4 main transformations: Rotation, Translation, Dilation and Reflection. Reflection is a transformation: flipping an object about a line. Reflection is distance-preserving transformation. The image has the same size as the original image ( in this case: ABC = A`B`C` ).The central line is called mirror line and here it is line BC. Answer: B. Reflection over segment BC.</span>
