Find the length of the line from A to C, which would be the radius using the distance formula:
Distance = √(-5 +1)^2 + 1+2)^2)
Distance = √(4^2 + 3^2)
Distance = √25
Distance = 5
The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^2, where h and k is the center point X and y values and r is the radius.
The center of the circle is located at A ( -1,-2) and the radius is 5.
Replace h, k and r with those values:
(x - (-1))^2 + (y- (-2))^2 = 5^2
Simplify to get:
(x+1)^2 + (y+2)^2 = 25
Answer:
approx. 251 in³
Step-by-step explanation:
The appropriate formula to use here is V = πr²h. Substituting 2 in for r and 5 in for h, we get:
V = π(2 in)^2·(5 in), or
V = π(4 in²)(5 in) = 80π in³, or approx. 251 in³
