Cylindrical

Diameter of 14, 40 feet long sketch the tank

Part 1) see the attached figure

Part 2)     or  

Step-by-step explanation:

The complete question is

A gas company’s delivery truck has a cylindrical tank that is 14 feet in diameter and 40 feet long.

1.  Sketch the tank, and mark the radius and the height.

2. How much gas can fit in the tank?

Part 1)  Sketch the tank, and mark the radius and the height.

we know that

The radius is equal to

----> the radius is half the diameter

The height is the same that the long of the cylinder

so

The sketch in the attached figure

Part 2) How much gas can fit in the tank?

we know that

To find out how much gas can fit in the tank, determine the volume of the cylinder

The volume of the cylinder is equal to

we have

substitute

----> exact value

assume

----> approximate value

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
