Finding the Volume of a Volleyball
The diameter of this beach ball is 12 inches.
Apply the formula for the volume of a sphere to
determine how much air it can hold. Use the calculator
to multiply by n. Round to the nearest hundredth.
Sphere V =
How much air can the beach ball hold?
1) Intro
Done

It can hold 904.78 in³ of air

Step-by-step explanation:

radius = 12/2 = 6

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius  = 6in

π = 3.14 16

V = ⁴⁄₃πr³

we replace the known values

V = ⁴⁄₃ * 3.14 * (6in)³

V = 4.1888 * 216 in³

V = 904.7808 in³

round to the nearest hundredth

V = 904.78 in³

The volume of the sphere is 904.78 in³

the correct functions are

h(x) = 3x + 2  

g(x) = 2^x

step-by-step explanation:

i proceed to calculate the different values ​​of k (x)

case 1)  k(x) = g(x) ∘ h(x)

g(x) ∘ h(x)=g(h(x))

k(x) = [2]^[3x + > is the option  4. k(x) = 2^(3x + 2 )

case 2)  k(x) = g(x) + h(x)

k(x) = [2^x]+[3x + 2]=2^x+3x+> is the option  1.) k(x) = 2^x + 3x + 2

case 3)k(x) = h(x) ÷ g(x)

k(x) =  [3x + 2]/[2^x]=3x/(2^x)+2/(2^x)=3x*(2^-x)+2^(1-x)

is the option  3.)   k(x) = (3x)2^(-x) + 2^(-x + 1 )

case 4)k(x) = g(x) - h(x)

k(x) =  [2^x]-[3x + 2]=2^x-3x-> is the option  2.) k(x) = 2^x - 3x - 2 

case 5)  k(x) = g(x) × h(x)

k(x) = [2^x]*[3x + > is the option  5.) k(x) = 2^x(3x + 2)

case 6)k(x) = h(x) ∘ g(x)

h(x) ∘ g(x)=h(g(x))

k(x)=3*[2^x]+> is the option  6. k(x) = 3(2^x) +2

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3
