Answer:

62.8 m^2

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h  where r is the radius and h is the height

V = (3.14) ( 2)^2 *5

V = 62.8 m^2

Volume of a Cylinder Formula: V = πr²h

  • <em>r</em> is radius
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>r</em> = 2 cm

<em>h</em> = 5 cm

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of a Cylinder Formula]:                               V = (3.14)(2 cm)²(5 cm)
  2. Evaluate exponents:                                                                                         V = (3.14)(4 cm²)(5 cm)
  3. Multiply:                                                                                                             V = (12.56 cm²)(5 cm)
  4. Multiply:                                                                                                             V = 62.8 cm³

Which linear function represents the line given by the point-slope equation y + 7 = –2/3(x + 6)?
Nuetrik [128]

Answer:

<em>First option: </em> f(x)=-\frac{2}{3}x-11

Step-by-step explanation:

Given the point-slope equation y+7=-\frac{2}{3}(x+6), you need to solve for y, because you are looking for the equation of the line in slope-intercept form:

y=mx+b

Being m the slope of that line, and b the intersection of the line with the y-axis.

Then:

Apply Distributive property:

y+7=-\frac{2}{3}x-4

Subtract 7 from both sides:

y+7-(7)=-\frac{2}{3}x-4-(7)\\y=-\frac{2}{3}x-11

Rewrite the equation:

f(x)=-\frac{2}{3}x-11 (The linear function of the First option)

What is the slope of the line y=3x-5
xeze [42]

Answer:

The y intercept and the slope are given in the equation. y=mx+b is slope-intercept form. mx is the slope and b is the y intercept. so in y=3x-5, 3x is the slope and -5 is the y intercept (what y is when x is zero).
