We have the following equation:
x2 + y2 + 6y - 72 = 0
Rewriting we have:
x2 + y2 + 6y = 72
Complete squares we have:
x2 + y2 + 6y + (6/2) ^ 2 = 72 + (6/2) ^ 2
x2 + y2 + 6y + (3) ^ 2 = 72 + (3) ^ 2
x2 + y2 + 6y + 9 = 72 + 9
x2 + (y + 3) 2 = 81
So, the center is:
(0, -3)
The radio is:
r = 9
Answer:
(0, -3)
r = 9
4.
This is because 4 goes into 16 4 times, hence 4 x 4 being 16.
Therefore, the answer would be four.

Answer:The area of the base will be (1)(3) m
The area of the right and left lateral faces will be (1)(2) = 2m
The area of the front and back lateral faces will be (2)(3) = 6m
The lateral area of the prism will be 16 m
Step-by-step explanation:
PT = 15, and TB = 10
Take the 15 from PT, and add the 10 from TB. Which equals 25.
PB = 25
So, 25 is your answer.
Hope this helps! ☺
The answer is 6 hope this helps
