[(284.1 x 105) - (1.100 x 10%)] x 2.8929

86,296.33523

Step-by-step explanation:

[(284.1×105) - (1.100×10%)] × 2.8929

=[29830.5 - 0.11] × 2.8929

=29830.39 × 2.8929

=86296.33523

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 !
