Step-by-step explanation:

Counting the digits after the point until we get to the 5:

The count is 3.

The power is -3:

5.03 * 10^-3.

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 !
