Find the volume of the composite solid below round your answer to the nearest cubic centimeter

It would be easier if we split the composite solid into a rectangular prism and a half of a cylinder.

The volume of the prism is easy: length * width * height: 35 * 9 * 42 = 13230 cm cubed.

The half of the cylinder is just: (pi * r^2 * h)/2

The diameter is 9, so the radius is 4.5. The height is 42. So:

(pi * 4.5^2 * 42)/2 is about 1335.96

1335.96 + 13230 = 14565.96 or, rounding up, 14566 cm cubed.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
