Answer:

62,500 pi

Step-by-step explanation:

diameter = radius + radius

d = 2r

r = d/2

A = 4pi r^2

= 4 pi (d/2)^2

= 4pi d^2/4

= 4pi* 250^2/4

= 4pi * 62,500/4

= 4pi * 15625

= 62,500 pi

Is (4,10) a solution to this system of equations? y=2x+2 y=10x+1
vladimir1956 [14]

Answer:

No

Step-by-step explanation:

To find out if (4,10) is a solution to the system, we plug in the values of x and y into each equation.

1:

  • 10=2(4)+2
  • 10=8+2
  • 10=10  

2:

  • 10=10(4)+1
  • 10=40+1
  • 10\neq 41

As you can see, (4,10) only satisfies ONE equation, not both. Therefore, the answer is no, it's not a solution.
