The value of x is 5/6 and y is 8/5.
Step-by-step explanation:
Given,
12x+15y=34 Eqn 1
-6x+5y=3 Eqn 2
Multiplying Eqn 2 by 2
Adding Eqn 1 and 3
Dividing both sides by 25
Putting y= 8/5 in Eqn 1
Dividing both sides by 12
The value of x is 5/6 and y is 8/5.

Answer:
7.07 cm
Step-by-step explanation:
we know,
circumference = 2πr
so,
2 × 22/7 × r = 66
44r = 66×7 = 462
r = 462/44 = 1.5
therefore, radius of the circle is 1.5 cm.
now,
we know , area = πr²
so,
22/7 × (1.5)²
22/7 × 2.25
49.5/7
7.07 cm (approx)
therefore, area of the circle is 7.07 cm (approx.)
hope this answer helps you!
