A volleyball of radius 13 inches fits exactly in a cylinder with the same radius. inside the container there is empty space not

asambeis [7]

Volume of Sphere is V=(4/3)*PI*r^3

The radius of the volleyball is 13 inches

So V=(4/3) * 3.14 * 13^3 = 9198 cubic inches

Volume of a cylinder is V=pi * r^2 *h

Since they say the ball fits perfectly

The radius is 13 and the height is 26 ( the diameter of the ball)

So V=3.14 * 13^2 * 26 = 13,797 cubic inches

13797 – 9198 = 4,599 cubic inches of empty space

A cone has a diameter of 7.5 ft and a height of 4.25 ft. What is the volume of the cone to the nearest tenth? Use 3.14 for π.

leva [86]

Answer:

The volume of a cone is $62.5\ \text{feet}^3$ .

Step-by-step explanation:

We have,

Diameter of a cone is 7.5 ft

Radius of a cone is 3.75 ft

Height of the cone is 4.25 ft

It is required to find the volume of the cone. The formula of the volume of cone is given by :

$V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\times 3.14\times (3.75)^2\times 4.25\\\\V=62.55\ \text{feet}^3$

So, the volume of a cone is $62.5\ \text{feet}^3$ .

Answer:

9) x=58

10) r=4

11) m=4

12) p=3

13) x=6

14) x=-3

15) s=400

Step-by-step explanation:

9) x+2/5=12

x5 x5

x+2=60

-2 -2

x=58

10) 7r + 14 - 3r =30

-14 -14

7r-3r=16

4r=16

÷4 ÷4

r=4

11) $\frac{4}{5}$ m+2=6

-2 -2

$\frac{4}{5}$ m=4

÷ $\frac{4}{5}$ ÷ $\frac{4}{5}$

m=4

12) 2(5p+9)=48

10p+18=48

-18 -18

10p=30

÷10 ÷10

p=3

13) 5(2x-8)=20

10x-40=20

+40 +40

10x=60

÷10 ÷10

x=6

14)6(3-2x)=54

18-12x=54

-18 -18

-12x=36

÷-12 ÷-12

x=-3

15) $\frac{2s}{5}$ - $\frac{s}{2}$ =40

x5 x5

2s- $\frac{s}{2}$ =200

x2 x2

2s-1s=400

1s=400
