Answer:
Let AB is the height of the cliff = H and p is the posit ion of the boat.Angle of depression= angle of elevation= 15 degrees therefore angle APB= 15 degrees tan 15=AB=h/1,000 h=(1,000)*tan 15=(1,000)(0.26794919243112)=268.94919243112 meters or

Answer:
576π in² and 1,809 in².
Step-by-step explanation:
To find the answer, the formula for the area of a circle, or A = πr², will need to be used.
In this question, we are only given the diameter. Simply divide by 2 to calculate the radius:
48/2 = 24 inches.
Now, plugging this into the equation for the Area of a Circle, gets us:
A = π24²
A = 576π or 1808.64 in².
Looking at the answer choices, we can choose 576π in² and 1,809 in² (as 1808.64 ≈1809)
-84= -4b -4(-7 -8b)
⇒ -84= -4b -4* (-7) -4*(-8b) (distributive property)
⇒ -84= -4b+ 28+ 32b
⇒ -84 -28= 32b -4b
⇒ -112= 28b
⇒ -112/28= b (inverse operation)
⇒ -4= b
Final answer: b= -4
Answer:
Step-by-step explanation:
The formula of a volume of a cylinder:
<em>r</em><em> - radius</em>
<em>H</em><em> - height</em>
