Either a or b. C and d don’t make sense cuz there’s no way those lines are perpendicular
Answer:
y = 4
Step-by-step explanation:
The exact
value of the given equation is 45 degrees or pi/4. I am hoping
that this answer has satisfied your query about and it will be able to help
you, and if you’d like, feel free to ask another question.
Volume of the cone is 117.5 π ft³
<u>Step-by-step explanation:</u>
Lateral area of the cone = πrs
s is the slant height = 15 ft
From the above formula, we can find the radius as, 5 ft.
Volume of the cone = π r² h/3
s = √ (5²+ h²)
Squaring on both sides, we will get,
s² = 15² = (5² + h²)
15² - 5² = h²
225 - 25 = 200 = h²
h = √200 = 14.1 ft
Volume = π × 5² × 14.1 / 3 = 117.5 π ft³
