I don’t understand. and someone please help?

givi [52]

Solution:

Note that:

6x + 26 = 92 (Vertically opposite angle)
92 + 92 + z + z = 360

Finding x.

6x + 26 = 92
=> 6x = 92 - 26
=> 6x = 66
=> x = 11

Finding z.

92 + 92 + z + z = 360
=> 184 + 2z = 360
=> 2z = 360 - 184
=> 2z = 176
=> z = 176/2 = 88

The lateral area of a right cylinder which has a base diameter of 12 cm and a height of 8 cm is?

garik1379 [7]

Answer:

$A = 301.59\ cm^2$ or $A=96\pi\ cm^2$

Step-by-step explanation:

The lateral area of a cylinder is calculated by the following formula

$A = 2\pi r * h.$

Where r is the radius of the right cylinder and h is the height

In this case we know that the diameter d of the cylinder is

$d=2r\\\\r=\frac{d}{2}\\\\r=\frac{12}{2}\\\\r=6\ cm$

$h=8\ cm$

Therefore the lateral area is:

$A = 2\pi*6 * 8.$

$A = 96\pi$

$A = 301.59\ cm^2$
