Answer:

  B.  π(3/2)²h

  (27/4)π cubic inches

Step-by-step explanation:

A. The formula for the volume of a cylinder is ...

  V = πr²h

The radius (r) is half the diameter, so for a diameter of 3 inches, the radius is 3/2 inches. When this is put into the formula, the volume is ...

  V = π(3/2)²h . . . . . . matches choice B

__

B. When h=3, the volume evaluates to ...

  V = π(9/4)(3) = (27/4)π . . . . cubic inches

The floor in the tool room measures 13 feet 3 inches by 11 feet 5 inches. What is the total area of the room in square feet? (Re
brilliants [131]

We have The floor in the tool room measures 13 feet 3 inches by 11 feet 5 inches.

Let us convert inches to feet since we want the area in square feet.

We know that 1 inch = 0.0833333 feet .

Therefore, we have

3 inches = 0.25 feet

5 inches = 0.42 feet

Thus, we have the below dimension in feet

Length =  13 feet 3 inches = 13+0.25 = 13.25 feet

Width = 11 feet 5 inches = 11+0.42 = 11.42 feet

Hence, area of the room is given by

A= \text{Length} \times \text{width}
\\
A=13.25 \times 11.42\\
\\
A=151.3 \text{ square feet}\\
A\approx 151 \text{ square feet}\\

a is the correct option.

which set of number could represent the length of the sides of a right triangle? A 9 11 14 B 15 18 21 C 7 24 25 D 8 9 10
EastWind [94]
Common Pythagorean triples include
  (3, 4, 5)
  (5, 12, 13)
  (7, 24, 25)
  (9, 40, 41)
The only Pythagorean triple that is an arithmetic sequence is (3, 4, 5), so any arithmetic sequence that is a Pythagorean triple must be a multiple of that, such as (9, 12, 15) or (15, 20, 25).

The arithmetic sequences of selections B and D are unrelated to the (3, 4, 5) triple, so cannot be Pythagorean triples. For selection A, we know that 9² + 11² = 81 + 121 = 202 > 14², so that is not a right triangle.

The appropriate selection is ...
  C. 7, 24, 25

There is a line that includes the point (4, 1) and has a slope of 1. What is its equation in
tino4ka555 [31]

Answer:

y = x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 1 , then

y = x + c ← is the partial equation

To find c substitute (4, 1 ) into the partial equation

1 = 4 + c ⇒ c = 1 - 4 = - 3

y = x - 3 ← equation of line
