Answer:
87.96 square inches
Step-by-step explanation:
The soup can is a cylinder, and we can find how many square inches the label will take up by finding the lateral surface area
Use the formula, LA = 2
rh
The diameter is 4 inches, so the radius is 2 inches
Plug in the radius and height into the formula, and solve:
LA = 2rh
LA = 2(2)(7)
LA = 28
= 87.96
So, the label will take up approximately 87.96 square inches
Point-slope form is y - y1 = m(x - x1). We just need to plug in our stuff. This gives us y - 9 = 4(x - 3). I am not sure if you need to simplify, but if you do, y - 9 = 4x - 12.
No, it would end up being 20a-32 which is not equivalent to 12a-6
Notice, it has a square base, so the base or bottom of the rectangular prism, is a square, that means, length = width = x, length and width both have the same value, let's say "x", check the picture below
