Answer:
where is the question
Step-by-step explanation:
no question ooo
Segment AB is a diameter of the sphere.
diameter = AB = 16 in.
radius = r = (16 in.)/2 = 8 in.
Volume of a sphere:
V = (4/3) * pi * r^3
V = (4/3) * (22/7) * (8 in.)^3
The water inside the bowl occupies half of the bowl, so the volume of the water is half the volume of the bowl.
Volume of water:
V = (1/2)(4/3)(22/7)(8^3) in.^3
Answer: Second choice.
Add up them up
Ab+BC
18.3+11.2
=29.5
Answer:
Step-by-step explanation:
Given that L is a line parametrized by

The plane perpendicular to the line will have normal as this line and hence direction ratios of normal would be coefficient of t in x,y,z
i.e. (2,3,-1)
So equation of the plane would be of the form

Use the fact that the plane passes through (2,0,-1) and hence this point will satisfy this equation.

So equation is

b) Substitute general point of L in the plane to find the intersecting point

i.e. same point given.
