The equation of any circle is
(x - a)^2 + (y - b)^2 = radius^2 where our center is (a, b)
Therefore, our equation is as follows.
(x + 2)^2 + (y - 3)^2 = 16
Answer:
see below
Step-by-step explanation:
Multiply by 2 and expand the right side:
2A = b1h +b2h
Subtract the b2 term:
2A -b2h = b1h
Divide by h:
b1 = (2A -b2h)/h
Answer:
10 feet
Step-by-step explanation:
18 × 2 = 36
56 - 36 = 20
20 ÷ 2 = 10
To check work, add all lengths together. 4 sides. 18 + 18 + 10 + 10 = 56
