5) In the figure, triangle ABC is a right triangle at B. If CD = 15, find BC to the nearest tenth.
ycow [4]

Answer:

BC ≈ 4.0

Step-by-step explanation:

∠ DCA = 180° - 70° = 110° ( adjacent angles )

∠ DAC = 180° - (30 + 110)° ← sum of angles in triangle

∠ DAC = 180° - 140° = 40°

Using the Sine rule in Δ ACD to find common side AC

\frac{AC}{sin30} = \frac{15}{sin40} ( cross- multiply )

AC × sin40° = 15 × sin30° ( divide both sides by sin40° )

AC = \frac{15sin30}{sin40} ≈ 11.668

Using the cosine ratio in right triangle ABC

cos70° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{11.668} ( multiply both sides by 11.668 )

11.668 × cos70° = BC , then

BC ≈ 4.0 ( to the nearest tenth )

What is the exact volume of the cylinder?
lesantik [10]
Volume of the cylinder=area (circle) x height
area (circle)=πr²
r=radius=4 in.
area=π(4 in)²=16π in²
height=8 in

Volume of the cylinder=(16π in²)(8 in)=128π in³≈402.12 in³

Answer=  128π in³        or        402.12 in³

Please please help im confused again
timama [110]

Answer:

A_s=179  \ yd

Step-by-step explanation:

Area of Circle can be calculated using following formula

A=\pi r^{2}

Where r is radius of circle

<u>Area of outer circle (r=11 yd)</u>

A_1=\pi (11)^{2}\\A_1=379.94 \ yd

<u>Area of inner circle (r=8 yd)</u>

A_2=\pi (8)^{2}\\A_2=200.96 \ yd

Area of shaded region

A_s=A_1-A_2

A_s=379.94-200.96\\A_s=179  \ yd
