Answer: I used to, but it got boring
Step-by-step explanation:
Add these eqn and then you have to cancel out (y) after that add x and 2x which is equal to 3x and also add RHS i.e.30 and divide it by 3
Answer:
area of circle=πr²=1.3mi²
we have
area of sector=∅/360×πr²
0.7mi²×360=∅1.3
∅=0.7×360/1.3=193.846°×π/180=387.7 radian
