Volume of a quadrangular pyramid=(1/3)bh
b=base
h=height

b=area of the base=area of a square=8.4 ft * 8.4 ft=70.56 ft²

Pythagoras theorem:
hypotenuse²=leg₁² + leg₂²

data:
hypotenuse=9.6 ft
leg₁=height=h
leg₂=8.4 ft /2=4.2 ft

(9.6 ft)²= h² + (4.2 ft)²
92.16 ft²=h²+17.64 ft²
h²=92.16 ft²-17.64 ft²
h²=74.52 ft²
h=√(74.52 ft²)=8.63 ft.

Volume of this quadrangular pyramid=(1/3)(70.56 ft²)(8.63 ft)=202.9 ft³≈202.3 ft³

Answer: ≈202.3 ft³

Coin resulted in heads

Student is selected at random from a class of six boys and sixteen girls.​

Desired outcomes:

16 girls, so D = 16

Total outcomes:

16+6 = 22, that is, 22 students, so T = 22

Probability:

P = \frac{16}{22} = 0.7273

D. 1.6 yd

Step-by-step explanation:

Use the law of sines.

\dfrac{c}{\sin C} = \dfrac{a}{\sin A}

\dfrac{c}{\sin 28^\circ} = \dfrac{2~yd}{\sin 36^\circ}

c = \dfrac{2~yd \times \sin 28^\circ}{\sin 36^\circ}

c = 1.6~yd
