Answer:

About 1249.366

Step-by-step explanation:

After plugging the circumference into the formula c=2π*r and solving, we get about 1249.366. You can round it however necessary :)

Hope I helped!

p.s: there's calculators online that can help you convert between circumference, diameter, area, and radius! Here's a link to one that I use!

Answer:

b =  \sqrt{65}

Step-by-step explanation:

{b}^{2}  +  {4}^{2}  =  {9}^{2}  \\  {b}^{2} + 16 = 81 \\  {b}^{2}   = 81 - 16 \\  {b}^{2}  = 65 \\ b =  \sqrt{65}

I hope I helped you^_^

I need help urgent this is to hard for me to do
Morgarella [4.7K]

Answer:

( 7 , 4 )

given:

  • 4x + 10y = 68
  • 4x - y = 24

make y the subject in equation 2:

4x - y = 24

-y = 24 - 4x

y = 4x - 24

insert this in equation 1:

4x + 10y = 68

4x + 10(4x - 24) = 68

4x + 40x - 240 = 68

44x = 68 + 240

44x = 308

x = 7

solve for y:

y = 4x - 24

y = 4(7) - 24

y = 4

Answer:

  (a)  no solution

Step-by-step explanation:

Writing the second equation in slope-intercept form, it becomes ...

  3x -y = 2 . . . . given

  y = 3x -2 . . . . add y-2 to both sides

The first equation is already in slope-intercept form:

  y = 3x +3 . . . . first equation

The coefficients of x in the two equations are both 3, so the lines they describe are parallel. They do not intersect, so there is <em>no solution</em>.
