Answer:
y = (-3/2) x + 3
Step-by-step explanation:
The line passes through (0, 3) and (2, 0)
Slope = (0 - 3)/(2 - 0) = -3/2
Let y = (-3/2) x + b
Use (0, 3) to get b:
3 = (-3/2)*0 + b, so b = 3
Then y = (-3/2) x + 3
Answer:
756π cm^3.
Step-by-step explanation:
Volume of the cone
270π = 1/3 π r^2 h
270π = 1/3 π r^2 * 10
r^2 = 270 / ( 10/3 )
r^2 = 81
r = 9 cm.
So the volume of the hemisphere = 1/2 * 4/3 * π * 9^3
= 486π cm^3.
So the volume of the whole solid = 270π + 486π
= 756 π cm^3.
