90,000 10years interest rate 6%

$54000

Step-by-step explanation:

To find the simple interest,

We multiply 90000 × 0.06 × 10

The interest is $54000

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 !
