Is that (4/4)^-3??

1^-3

Which is basically 1...

Answer:

Ok so what you are suppose to do is find the area

Step-by-step explanation:

Which here is an explanation of how to find area (The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.)

Answer:

1017.4 m³

Step-by-step explanation:

Volume of cone V = (1/3)πr²h

pi = 3.14

r = 9 and r² = 81 m²

h = 12 m

V = (1/3)*3.14*81*12

V = 1017.36 rounded 1017.4 m³, which is the first answer.
