What is the area of a trapezoid that has bases of 1 1/4 feet and 14 inches and a height of 3 inches? 43.5 in. 2 87 in. 2 22.9 in
PolarNik [594]
The area of a trapezoid is the average of the bases times the height, mathematically:

A=h(b1+b2)/2, in this case:

A=3(1.25ft(12in/ft)+14)/2

A=3(29)/2

A=43.5 in^2

Answer:

The volume of a cylinder:

V \approx 150.796 ft^3

Step-by-step explanation:

To find the volume of a cylinder, you need the this formula:

V = \pi r^2h

-Use the given height and radius for the formula:

V = \pi 4^2 3

-Then, solve the formula:

V = \pi \times 4^2 \times 3

V = \pi \times 16 \times 3

V = \pi \times 48

V = 48\pi \approx 150.796

So, the volume of a cylinder is approximately 150.796 ft^3 .
