If h = 12 units and r = 3 units, then what is the volume of the cone shown

36π cubit units

Step-by-step explanation:

To find the volume of a cone, use the formula given below.

Volume: 1/3 X area of circular base x height

First, find the area of the circular base.

Area of Circular Base =  πr²

                                   = π(3 units)²

                                   =9π square units

Next, use this result along with the formula given above to find the volume of the cone.

Volume = 1/3 x area of circular base x height

             = 1/3 x (9π square units) x (12 units)

             = 36 π cubit units

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
