Answer:

72

Step-by-step explanation:

Circumference of a circle = 2πr

Area of a circle: πr^2

Plug in:

C = 2πr

30.1 = 2(3.14)r

30.1 = 6.28r

r = 4.79 (Dividing both sides by 6.28)

Use area of the circle:

A = 3.14(4.79)^2

= 72.044474

Round to nearest whole number = 72

Select the equations of the lines that are parallel to the line whose equation is y= 3x +5.
Andru [333]

Answer:

-3x + y = 8.

3y = 9x.

Step-by-step explanation:

To find the slope of the lines we convert to slope-intercept form, which is

y = mx + c   (m is the slope.)

The slope of y = 3x + 5 is therefore 3.

Parallel lines have the same slope.

Finding the slope of the given lines:

-3x + y = 8

y = 3x + 8  - slope is 3 so this is parallel to  y = 3x + 5.

3y = 9x

Divide through by 3:

y = 3x  - so this is also parallel to 3x + 5.

y = -jx  The slope is -j so it is not parallel.

16x + 2y = 12

2y = -16x + 12

y = -8x + 6  - Not parallel.
