Acone has a diameter of 23 inches and a height of 19.7 inches. select all of the expressions that could be used to find the volume of the cone in cubic inches? use 3.14

2727

Step-by-step explanation:

The formula for finding the volume of a cone is

1/3πr²h

The radius would be 11.5 because, radius equals the diameter divided by two.

So, first you would plug your numbers into the equation

1/3(π)(11.5)²(19.7)

*use 3.14 for pi

Then multiply.

V = 2726.9 (2727 if you round to the nearest whole number)

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

no not all of them.

step-by-step explanation:

some of them have a square base.
