Hey there! I'm happy to help you!
The formula for the volume of a cone is V=1/3(πr²h). Now, to make it look ungibberishy and all numbery...
The volume of the cone is equal to the area of the base (the circle on the bottom whose area formula is pi multiplied by the radius squared) multiplied by the height and then divided by three.
In our case, though, we already have the volume. We need to undo the equation so that we can find the area of the circle base.
In our equation the last thing we do is divide by three. So, we will want to multiply by three to undo this.
4,170*3= 12510
The other step we took was multiply the base by the height, which is 20 centimeters. To get our base, we will divide by the height instead!
12510/20= 625.5
Therefore, the area of the base of the cone is 625.5 centimeters squared.
I hope that this helps! Have a wonderful day!
