If you know that 7×8=56 how can you use the commutative (order) property of multiplication to find the product of 8×7

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

i belive those are the ones that are under 90 degreese.
