Answer:
B. (x +4)² +(y +5)² = 64
Step-by-step explanation:
The equation for a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
Filling in your given values, you have ...
(x -(-4))² +(y -(-5))² = 8²
Simplifying, you get ...
(x +4)² +(y +5)² = 64 . . . . . . . matches choice B

Given
Base Dimension
Required
The base area of all containers
First, calculate the base area of 1 container.
This is calculated as:
Express as improper fraction
So, we have:
The number of containers is not given. So, I will use 'n' as the number of containers.
So, we have:
