What is the volume of the item described? an ice cream cone with a cone of radius 2 cm and height of 9 cm with a hemisphere of ice cream on top of radius 2 cm. select the exact answer in terms of π and the approximate answer rounded to the nearest whole number. 147 cm³ 683π cm³ 1403π cm³ 71 cm³ 523π cm³ 54 cm³

The exact volume of ice cream cone is cm³

and approximate value of ice cream cone is 54 cm³

Step-by-step explanation:

Given :   An ice cream cone with a cone of radius 2 cm and height of 9 cm with a hemisphere of ice cream on top of radius 2 cm.

We have to find the volume of the item described.

Below is the image of ice cream cone.

Volume of ice cream cone is given by volume of cone and volume of hemisphere.

Volume of cone =

radius given (r) = 2 cm

Height (h) = 9 cm

Volume of cone =

Simplify, we get,

Volume of cone =

Also, volume of hemisphere =

radius given (r) = 2 cm

volume of hemisphere =

volume of hemisphere =    

Thus, The exact volume of ice cream cone is and approximate value of ice cream cone is 54 cm³

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
