Answer:
Step-by-step explanation:
2) l = 9 cm
b = 7 cm
h = 3 cm
Surface Area= 2*(lb + bh + hl)
=2*(9*7 + 7*3 + 3*9)
=2*(63 + 21 + 27)
= 2 * 111
= 222 cm²
Answer:
(-3, 1), 5
Step-by-step explanation:
x² + y² + 6x - 2y - 15 = 0
Rearrange:
x² + 6x + y² - 2y = 15
Complete the square:
x² + 6x + 9 + y² - 2y + 1 = 15 + 9 + 1
(x + 3)² + (y - 1)² = 25
Therefore, the center is (-3, 1) and the radius is 5.
