g(x) = -3x² - 2x + 3
g(-2) = -3(-2)² - 2(-2) + 3
g(-2) = -12 + 4 + 3 = -5
The volume of the cone is
one-third of the volume of the cylinder which is equal to the product of area
of the base and the height. The equation is,
<span> V = (1/3)(pi)(r^2)h </span>
Dividing both sides of the
equation by (1/3)(pi)(h) will give us,
<span> 3V/(pi)(h) = r^2</span>
Taking the square-root of
both sides,
<span> r = sqrt(3V/(pi)(h))</span>
Answer:
It will be 72cm
Step-by-step explanation:
Volume of a rectangular prism = (length x width x height) cubic units.
9x4x2=72
First you have to use the formula which is r to the second times height times pi
You would do 4 times 2 equals 8 then multiply 8 times 10 equals 80 then multiply that answer times 3.14 then your answer is 251.2
Answer:
B. 50.2ft^2
Step-by-step explanation:
π r^2
=3.14×(8/2)^2
=3.14×16
=> 50.2 ft^2
hope it helps..
have a great day!!
