What is the area of this trapezoid? Enter your answer in the box.

mezya [45]

Answer:

352 ft²

Step-by-step explanation:

The formula for the area of a trapezoid is $A=(\frac{b_1+b_2}{2})h$ where $b_1$ and $b_2$ are the bases of the trapezoid and $h$ is the height, thus:

$A=(\frac{b_1+b_2}{2})h\\\\A=(\frac{13+31}{2})(16)\\\\A=(\frac{44}{2})(16)\\ \\A=(22)(16)\\\\A=352$

This means that the area of the trapezoid is 352 ft².

a mailing tube in the shape of cylinder has a height of 24 inches and a radius of 3 inches. what is the volume, in cubic inches,

TiliK225 [7]

ANSWER

The volume of the mailing tube is 678.6 square inches to the nearest tenth.

EXPLANATION

The volume of a cylinder is calculated using the formula;

$V=\pi \: {r}^{2} h$

Since the mailing tube is in the form of a cylinder, we use this formula to find its volume.

We substitute h=24 and r=3 to obtain,

$V=\pi \times {3}^{2} \times 24$

$V=216\pi {in}^{2}$

$V=678.6{in}^{2}$
