A circle’s circumference is approximately 44 cm. Complete each statement. Use 3.14 for π. The circle’s diameter is approximately
cm.

The circle’s radius is approximately
cm.

The circle’s area is approximately
cm 2 .

The circle’s diameter is approximately 14 cm.

Circumference equals 2πr

44 divided by 2 equals 22

22 divided by 3.14 equals 7.00

Diameter equals 2r

7 times 2 equals 14

The circle’s radius is approximately 7 cm.

The circle's area is approximately 153.86 cm 2

Area equals pi r squared

3.14 times 7 squared equals 153.86

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

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

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
