<h2>Answer:</h2>

<u>The correct answer is </u><u>B) 78.5</u>

<u></u>

<h2>Step-by-step explanation:</h2>

As we know that

Area of a circle = π (r) ²

Radius will be 1/2d

Radius is 5 inches

So putting the values

Area = 3.14* 25

Area = 78.5398163397

Volume of the cylinder is 480 cm³ (rounded off to the nearest tenth)

Step-by-step explanation:

  • Step 1: Find volume of the cylinder when radius = 4 cm and height = 9.5 cm

Volume = πr²h = 3.14 × 4² × 9.5

             = 3.14 × 16 × 9.5 = 477.28 cm³ ≈ 480 cm³

For this case we have that the point-slope equation of a line is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It is the slope of the line

(x_ {0}, y_ {0}): It is a point through which the line passes

In this case we have to:

(x_ {0}, y_ {0}) :( 3,2)

Substituting in the equation we have:

y-2 = m (x-3)

Answer:

y-2 = m (x-3)

We just need to replace the value of the slope
