Find the SLANT HEIGHT of the pyramid, then calculate its SURFACE AREA.

Vedmedyk [2.9K]

Answer:

13 cm

Step-by-step explanation:

slant height = $\sqrt{12^2 +\frac{10^2}{4} }$

= $\sqrt{144 + \frac{100}{4} }$

= $\sqrt{144 + 25}$

= $\sqrt{169}$

=13 cm

a=10 cm

l =

surface area = $a^{2} + 2a \sqrt{\frac{a^{2} }{4} +h^{2} }$

= $10^{2} +2*10 \sqrt{\frac{10^{2} }{4} +12^{2} } \\100 + 20 \sqrt{\frac{100}{4} + 144} \\100 + 20\sqrt{25 + 144} \\100 + 20 \sqrt{169} \\100 + 20*13\\100 + 260\\360 cm^2$

Let 2x-5y=16 and 5x+3y=9. what is the value of 12x+y

kari74 [83]

2x-5y=16 =>10x-25y=80
5x+3y=9 => 10x+6y=18
subtract one from the other: (6-(-25)y=(18-80), 31y=-62, y=-2
plug y=-2 in 2x-5y=16 to find x: 2x+10=16, x=3
12x+y=12*3-2=34
