Question

sammi's brother again

The area of this cylinder's base is one hundred fifty square inches. The height of the cylinder is 6 inches. What is the volume of the cone that has the same base area and height?

Answer 1

area * height

Answer 2

that is it?

Answer 3

yea

Answer 4

oops no

Answer 5

oh ok

Answer 6

it's (1/3) area * height.

I thought it was a cylinder

Answer 7

wuld it be 300

Answer 8

@sourwing

Answer 9

idk if you did the math right

Answer 10

The formula for the volume of a cylinder is:
V1 = π(r^2)h
and πr^2 is the same thing as the base area. Since we're given that that is 150, we can find the radius:
πr^2 = 150
r^2 = 150/π
r = √(150/π)
And we're given that the height is 6, so we don't need to solve anything.

The volume of a cone is:
V = (π/3)(r^2)h
Plugging in r = √(150/π) and h = 6 results in:
V = (π/3)(√(150/π)^2)(6)
V = (π/3)(150/π)(6)
V = 300

So the answer is 300 cubic inches.

Answer 11

@sammixboo ur correct

Answer 12

ok thnx

Answer 13

volume of cone = 1/3 ( volume of cilindrical)
( volume of cilindrical) = base area * hight = 150*6=900
thats it @Elsa213 no need for more calculation

Answer 14

ohhh ohh a cone... ok so

Answer 15

V = 1/3*b*h

V = 1/3*150*6

V = 1/3*900

V = 300

that is what i put

Answer 16

?
