Answer with Step-by-step explanation:
V=kr²h
Where r is the radius and h is the height of the cylinder
Cylinder A has a volume of 251.2 cubic inches and has a radius of 4 inches and a height of 5 inches.
⇒ 251.2=k×4²×5
⇒ 251.2=80k
⇒k=251.2/80
⇒ k=3.14
We have to find volume of cylinder B, which has a radius of 3 inches and a height of 9 inches
r=3 inches
h=9 inches
V=3.14×3²×9
=254.34 cubic inches
Hence, Volume of cylinder B is:
254.34 cubic inches
Answer:
<em>m=-1/2</em>
Step-by-step explanation:
The equation is in y=mx+b form. M is the slope. In this equation, -1/2 is m.
Therefore the slope is -1/2.
Answer:
f(- 9) = 2
Step-by-step explanation:
f(- 9) is asking for the value of y when x = - 9
Locate x = - 9 on the x- axis
Then go vertically up to meet the graph at (- 9, 2 )
Thus when x = - 9, y = 2 , that is
f(- 9) = 2
