12.56. The formula for the area of a circle( radius squared time pie) No, when u double the radius the area quadruples because your squaring the radius.
Answer:
B
Step-by-step explanation:
3x - 2y = 8 → (1)
x + y = 6 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate y
2x + 2y = 12 → (3)
Add (1) and (3) term by term to eliminate y
(3x + 2x) + (- 2y + 2y) = (8 + 12) , that is
5x + 0 = 20
5x = 20 → B
