3. Find the volume of the pyramid.

Gnoma [55]

Answer:

$916.11\:ft^{3}$

Step-by-step explanation:

Volume of the hexagonal pyramid = $1/3\times (area\: of \: hexagonal\:base)\times height$

Here sides of hexagonal base = 9 ft

So, Area of hexagon = $6\times \frac{\sqrt{3} }{4} a^{2}$

$6\times \frac{\sqrt{3} }{4} \times 9 \times 9$

$= 210.5$

Height is given, 13 ft

So, volume = $1/3\times 210.5\times 13$

$= 916.11\: ft^{3}$

angle EFG and angle GFH are a linear pair, m angle GFH= 2n+38 and m angle GFH=2n+38. what are m angle EFG and m angle GFH

motikmotik

Answer:

Part 1) m∠EFG=94°

Part 2) m∠GFH=86°

Step-by-step explanation:

we know that

m∠EFG+m∠GFH=180° -----> by linear pair (given problem)

we have

m∠EFG=3n+22

m∠GFH=2n+38

substitute the values

(3n+22)°+(2n+38)°=180°

Solve for n

(5n+60)=180

5n=180-60

5n=120

n=24

Find the measure of angle EFG

m∠EFG=3n+22

substitute the value of n

m∠EFG=3(24)+22=94°

Find the measure of angle GFH

m∠GFH=2n+38

substitute the value of n

m∠GFH=2(24)+38=86°
