Answer:
Step-by-step explanation:
From the given information, the symmetric equations for the line pass through(4, -5, 2) i.e () and are parallel to
The parallel vector to the line i + zj+k = ai + bj + ck
Hence, the equation for the line is :
x = 4 + t
y = -5 + 2t
z = 2 + t
Thus, x, y, z = ( 4+t, -5+2t, 2+t )
The symmetric equation can now be as follows:
∴
Answer:
6 = r
Step-by-step explanation:
V = πr³ Use this equation to find the volume of a hemisphere
144π = πr³ Divide both sides by
π
216 = r³ Take the cube root of both sides
6 = r
