Answer:
20/3
Step-by-step explanation:
(3/8)*(10/9)*16
This is 30/72 = 5/12
5/12*16=20/3
Answer:
The volume inside the cylinder is
.
Step-by-step explanation:
Given : Four spheres of radius 6 cm just fit inside a cylinder.
To find : Calculate the volume inside the cylinder that is empty ?
Solution :
The volume of the cylinder is volume of 4 spheres.
The volume of sphere is ![V=\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
The radius is 6 cm.
The volume of four spheres is
![V=4\times \frac{4}{3}\times \pi\times (6)^3](https://tex.z-dn.net/?f=V%3D4%5Ctimes%20%5Cfrac%7B4%7D%7B3%7D%5Ctimes%20%5Cpi%5Ctimes%20%286%29%5E3)
![V=1152\pi\ cm^3](https://tex.z-dn.net/?f=V%3D1152%5Cpi%5C%20cm%5E3)
Therefore, the volume inside the cylinder is
.
Answer:
let c is a point between a and b we can find the coordinates of c by using mid-point formula
the coordinate x of c is equal to
x=(x1+x2)÷2
x=(3+27)÷2
x=30÷2
x=15
the coordinate y of c is equal to
y=(y1+y2)÷2
y=(2+30)÷2
y=32÷2
y=16
so the coordinates of c are (15,16)
The circumference equals diameter x pie which equals:
