Answer:
w > -3
Step-by-step explanation:
2w<9+5w
Subtract 5w from each side
2w-5w<9+5w-5w
-3w <9
Divide each side by -3 remembering to flip the inequality
-3w/-3 > 9/-3
w > -3
Answer:
Volume of the frustum = ⅓πh(4R² - r²)
Step-by-step explanation:
We are to determine the volume of the frustum.
Find attached the diagram obtained from the given information.
Let height of small cone = h
height of the large cone = H
The height of a small cone is a quarter of the height of the large cone:
h = ¼×H
H = 4h
Volume of the frustum = volume of the large cone - volume of small cone
volume of the large cone = ⅓πR²H
= ⅓πR²(4h) = 4/3 ×π×R²h
volume of small cone = ⅓πr²h
Volume of the frustum = 4/3 ×π×R²h - ⅓πr²h
Volume of the frustum = ⅓(4π×R²h - πr²h)
Volume of the frustum = ⅓πh(4R² - r²)
Answer:
Question 1 is, the blue figure is larger than the red figure
Question 2 is, the red and the blue figure are equal
Find the answer that best represents that
The computation is that the height of the sail is 15 yards.
<h3>How to calculate the height?</h3>
From the information, it was stated that the longest edge of the sail measures 17 yards, and the bottom edge of the sail is 8 yards.
We can use the Pythagoras theorem. Therefore,
c² = a² + b²
17² = 8² + b²
b² = 17² - 8²
b² = 289 - 64
b² = 225
b = ✓225
b = 15
Therefore, the computation is that the height of the sail is 15 yards.
