igor_vitrenko [27]

Answer:

Volume of prism = 39 km cubed

Step-by-step explanation:

<u>IMPORTANT FORMULA: Volume of any prism = Area of base * Height </u>

<u />

In this case, <u><em>the area of the base</em></u> means <u><em>the area of the trapezoid. </em></u>

Area of trapezoid = base1+base2/2  * height

Area of trapezoid = 8+5/2  * 1.5

Area of trapezoid = 13/2  * 1.5 = 9.75

We already know that the height of the trapezoidal prism is 4 kilometers.

So, we have all of the values that are needed to correctly fill in the formula.

Volume of the prism = 9.75 * 4 = 39

Answer:

Step-by-step explanation:

(1). A = π r²

A = 4 π

Area of shaded region is \frac{4\pi *260}{360} = \frac{26}{9} \pi or \frac{26\pi }{9}

(2). C = 4 π

In this case, the length of the bigger arc and the area of shaded region happen to be the same.

The length of the arc ADB is  \frac{26}{9} \pi or \frac{26\pi }{9}
