A spherical scoop of ice cream is placed on top of a hollow ice cream cone. the scoop and cone have the same radius. the ice cre
noname [10]
The figure shown below illustrates the problem.

The volume of the empty cone is
V₁ = (1/3) π r²h

The volume of the sphere is
V₂ = (4/3) π r³

Because the melted ice cream completely fills the cone, therefore
V₁ = V₂
(1/3) π r² h = (4/3) π r³
Divide each side by (1/3) π r².
h = 4r

Answer:
The height of the cone is 4 times greater than the radius f the cone.

Find the volume of the cone shown below.
BlackZzzverrR [31]

Answer:

D

Step-by-step explanation:

The formula for volume of cone is  V=\frac{1}{3}\pi r^2 h

Where

V is the volume

r is the radius of the circular base

h is the height of the cone

<em>In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):</em>

<em>V=\frac{1}{3}\pi (9)^2(12)\\=324 \pi</em>

<em />

<em>correct answer is D</em>

inessss [21]

Answer:

the correct option is p≥75

Step-by-step explanation:

the correct answer ir p≥75 because the sum of all other task she have done

$150+$65+$120+$100+$90=$525 so in order to reach $600(the amount she needs to pay her bills) u need to rest:

$600-the sum of the other 5 works ---> $600-$525=75 ----> this means that $75 is enough to pay her bills, but if she earns more than that it would be enough too.

ANWER= p≥75(higher or equal to 75)
