Answer:

Step-by-step explanation:
step 1
Find the volume of the cylindrical can
The volume of the cylinder is equal to

we have

substitute the values

step 2
Find the volume of the cylindrical glasses
The volume of the cylinder is equal to

we have

substitute the values

Find the volume of 3/4 of the glass

step 3
Divide the total volume of cylindrical can by the 3/4 volume of the glass

-1.96312 is larger than -5
in a number line, when it is positive, the larger the number is bigger than the smaller.
however, when it is negative, the smaller number is bigger than the larger.
hope this helps
Answer: 111.4m
Explanation:
1) Trigonometric ratios
You only need to use tangent ratio.
tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance
2) First, find the height of the ballon when he is watching at an angle of elevation of 28°
tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance
tan(28°) = balloon height/65m ⇒balloon height = tan(28°)×65m
balloon height = 34.56m
3) Second, find the height of the balloon,when he is watching at an angle of elevation of 66°
tan(66°) = height of the balloon / 65m ⇒ height of the balloon = tan(66°)×65m
height of the balloon = 145.99m
4) Vertical distance the balloon ascended while Charlie watched.
Subtract the final initial height from the final height:
145.99m - 34.56m = 111.43m
4) Round to the nearest tenth: 111.4 m
