153.9 inches is the correct answer
Ann [662]3 years ago
3 0

Answer:

153.9 in²

Step-by-step explanation:

Using the formula: A = π r²

Where r = the radius and π is 3.14.

The radius is the diameter divided by 2.

14 divided by 2 is 7.

Plug in 7 into the formula:

A = π 7²

7² is 49.

49 times π is equal to 153.86.

Rounding this up to the nearest tenth, you'll get 153.9

find the equation of a line through the coordinate (3,6) and parallel to the line represented by y=5/3 x-1
maw [93]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0 or (0,y))


For lines to be parallel, their slopes have to be the SAME.


The given line's slope is 5/3, so the parallel line's slope is also 5/3

y = 5/3x + b

To find "b", plug in the point (3,6) into the equation

y = 5/3x + b

6 = 5/3(3) + b

6 = 5 + b

1 = b


y = 5/3x + 1

What is the slope y+2=1/4(x-3)
ioda

Answer:

m=\frac{1}{4}

Step-by-step explanation:

Given

y+2=\frac{1}{4}(x-3)

Required

Find the slope

y+2=\frac{1}{4}(x-3)

Subtract 2 from both sides

y+2-2=\frac{1}{4}(x-3) - 2

y=\frac{1}{4}(x-3) - 2

Open bracket

y=\frac{1}{4}x-\frac{1}{4}*3 - 2

y=\frac{1}{4}x-\frac{3}{4} - 2

Take LCM

y=\frac{1}{4}x+\frac{-3 - 8}{4}

y=\frac{1}{4}x+\frac{-11}{4}

y=\frac{1}{4}x-\frac{11}{4}

An equation has the form:

y = mx + b

Where

m = slope

By comparing: y = mx + b and y=\frac{1}{4}x-\frac{11}{4}

m=\frac{1}{4}

<em>So, the slope is 1/4</em>
