If r=4cm and h= 4cm, what is the volume of the cone

volume cone = 1/3 pi r^2 h

volume cylinder = pi r^2 h

Step-by-step explanation:

1.  Volume = 1/3 x pi x r^2 x h = 12 X pi

2.  100 pi = 1/3 x pi x r^2 x 12

r^2 = 25

r = 5 cm

3.  volume = pi x 16 X 5 = 80 pi cubic meters

4.  400 pi = pi x r^2 X 4

r^2 = 100

r = 10 yards

what do u need to know

step-by-step explanation:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
