A = pi(r) ^2
A = 3.14(5) ^2
A = 15.7 ^2
A = 246.49
Hope this helps.
Answer:

Step-by-step explanation:
We have

Put the coordinates of the given points and check the inequality:
For (0; 5) → x = 0; y = 5

For (2; 4) → x = 2, y = 4

For (1; 3) → x = 1, y = 3

Answer:
Step-by-step explanation:
1. 7x + 4
2. 3x - 2
2x-13+3x-8+2x-3+2x-7+3x-1+2x+11+2x+9= (7-2)×180
16x-12=(7-2)×180
(7-2)×180 Work this out on a calculator
And then that answer=16x-12
Then you solve by adding 12 both sides and dividing by 16 both sides to get what x is.
