The diameter of a basketball is 24 centimeters. find the volume of the basketball
MatroZZZ [7]

Answer:

2304π cm³

Step-by-step explanation:

The formula for the volume of a sphere is: 4πr³/3

The equation gave us the diameter so we can find the radius right away: 24 ÷ 2 = 12

Plug the radius in to the formula:

4π12³/3 = (4×1728π)/3

= 6912π/3

= 2304π

A box contains marbles of five different colors: red, green, blue, yellow, and purple. there is an equal number of each color. a
olga nikolaevna [1]
P(red) = 1/5     [that says "probability of getting red is one fifth"
P(green) = 1/5
P(blue) = 1/5
P(yellow) = 1/5
P(purple) = 1/5

The reason the fractions are all the same is that there are equal numbers of each color.  For example, if there were 7 marbles of each color, there would be a total of 35 marbles.

P(red) = 7/35 = 1/5
Similar for the other colors.

If one root of the equation is 4x^2- 2x+p-4 be the reciprocal of other. then find the value of p​
SashulF [63]

Answer:

p = 8

Step-by-step explanation:

Let one root of the eqn. be alpha . Other root is 1/alpha .

We know that product of both roots of an quadratic eqn. is c/a where "c" is the co-efficient of the constant  & "a" is the co-efficient of x^2.

Here "c" is p-4 & "a" is 4. And the product of roots is 1 ( ∵ prdouct of a number and its reciprocal is 1 )

\frac{c}{a} = 1\\=> \frac{p - 4}{4} = 1\\=> p - 4 = 4\\=> p = 4 + 4 = 8
