Answer:
100.5cm2
Step-by-step explanation:
v=pi(r)2(h)
v=3.14(2)2(8)
v=3.14(4)(8)
v=100.48
v=100.5cm2
Answer:
h=-6 k=-30
Step-by-step explanation:








We have to write

In log form
To convert exponential equation to log equation, we have to use the following rule
So we will get

or

And that's the required log form .
Answer:
Volume of Cone =

Thus, Volume = 16.75 cubic feet
Step-by-step explanation:
Volume of a cone is given by the formula

Where r is the radius and
h is the height
Given radius r = 2 and
height is 2 times that.
So height is 2*2 = 4
Plugging these into the formula we get:
Volume of Cone =

Thus, Volume = 16.75 cubic feet
