It's pretty simple to find the answer. To find the geometric mean of two numbers you have to multiply them and then calculate the square root of the resulting product. So the answer is 16.43

MATH QUESTION!! PLEASE HELP

svlad2 [7]

bro i literally had the same question about this

you in honors or something? sry i only got A

I might have B later on or something

Answer:

41.125π ≈ 129

149.875π ≈ 471

Step-by-step explanation:

Surface area of smaller ganza:

3.5/2 = 1.75 x 1.75 = 3.0625 x 3.14 = 9.61625 x 2 = 19.2325

1.75 x 10 = 17.5 x 3.14 = 54.95 x 2 = 109.9 + 19.2 = 129 (Rounded)

Surface area of larger ganza:

5.5/2=2.75 x 2.75 = 7.5625 x 3.14 = 23.74625 x 2 = 47.4925

2.75 x 24.5 = 67.375 x 3.14 = 211.5575 x 2 = 423.115 + 47.4925 = 471 (Rounded)

129/3.14 = 41.125

471/3.14 = 149.875

Answer:

The answer is " $\bold{17456.6 \ ft}$ "

Step-by-step explanation:

Please find the complete question in the attached file.

$\sin \theta = \frac{P}{h}\\\\\to BC =x\\\\\to BD =y\\\\$

The height of tower (AB) = 300 ft

Distance = CD

$\Delta ABC \\\\\sin \theta = \frac{AB}{AC}\\\\\sin (2.5) = \frac{300}{AC}\\\\Ac= \frac{300}{\sin (2.5)}\\\\AC= 6877.68 \\\\\Delta ABD \\\\\sin \theta = \frac{AB}{AD}\\\\\sin (1.3) = \frac{300}{AD}\\\\AD= \frac{300}{\sin (1.3)}\\\\AC= 1322.33$

calculating CD :

$CD^2 = AC^2 +AD^2 -2\cdot AC \cdot AD \cdot \cos(117^{\circ}) \\\\CD = \sqrt{(6877.68)^2 +(13223.23)^2 -2\cdot (6877.68) \cdot (13223.23) \cdot \cos(117^{\circ})}\\\\CD =\sqrt{47302482.1824 + 174853811.6329 - 82576463.207}\\\\CD= \sqrt{304732757.02}\\\\CD= 17456.6 \ ft$
