Answer:

option 3, 972\pi in^{3}

Step-by-step explanation:

The formula to find the volume of a sphere is \frac{4}{3} \pi r^{3}

where r os the radius

given: diameter = 18in

radius = diameter / 2

radius = 18 / 2

r = 9in

Plug in radius:

\frac{4}{3} \pi (9)^{3}\\\\\frac{4\pi (9)^{3}}{3} \\\\Factor (9)^{3}: (3)^{6}\\\\\frac{(3)^{6} * 4\pi }{3} \\\\

cancel common factor: 3

3^{5} * 4\pi \\3^{5} = 243\\243 * 4\pi\\972\pi

Johnny has a bag with 84 coins in it. If the ratio of dimes to nickels to pennies is 3 to 2 to 1, how many
omeli [17]

Answer:

28

Step-by-step explanation:

Number of coins in the bag ⇒ 84

Give that,

Dimes : Nickels : Pennies

  3       :       2     :   1

You can see that, there are 6 parts . ( 3 + 2 + 1 = 6 )

And now let us write the types of coins in fractions.

Dimes ⇒  \frac{3}{6}

Nickels ⇒ \frac{2}{6}

Pennies ⇒ \frac{1}{6}

And now they're asking for the number of nickels.

To find that, you can multiply 84 ( number of coins) by it's fraction ( 2/6).

Let us solve.

84 × \frac{2}{6}

\frac{84*2}{6}

\frac{168}{6}

28

Therfore, there are 28 nickels.
