Acone-shaped pile of gravel has a diameter of 30 m and a height of 9.1 m.
which estimate best approximates the volume of the pile of gravel?
2120 m³
2600 m³
6360 m³
8480 m³

 The correct option is (A) 2120 m³.

Step-by-step explanation:  Given that a cone-shaped pile of gravel has a diameter of 30 m and a height of 9.1 m.

We are to select the correct option that estimate best approximates the volume of the pile of gravel.

The VOLUME of a cone with radius 'r' units and height 'h' units is given by the formula:

In the given cone-shaped pile, diameter of gravel is 30 m, so its radius will be

and height, h = 9.1 m.

Therefore, the volume of the cone-shaped pile is

Out of the given options, only 2120 is the nearest one, so the best approximate will be 2120 m³.

Thus, (A) is the correct option.

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
