7.55555556 is a mother way to put 7 5/9
Answer:
First, you have to find out the surface area of the box
=> Sbox = 10 x 5 x 2 + 10 x 8 x 2 + 5 x 8 x 2 = 340
Denote Surface area of the ball as Sball, we have:
Sball + Sbox = 352.56
=> Sball = 352.56 - Sbox = 352.56 - 340 = 12.56
From the formula to calculate Sball, we have:
4 x pi x radius^2 = 12.56
=> radius^2 = 12.56/(4 x pi) = 1 (here, pi = 3.14)
=> radius = 1 in
Hope this helps!

Multiply the first equation by 4:-
we get 4y = 8x - 32
Compare that with 4y = lx - 32 and we see that k = 8 Answer
Answer:
It's B
Step-by-step explanation:
Because I randomly guessed and that was the answer.
The equation you use for the slope of this kind of problem is (y2-y1)/(x2-x1). x1 is the first X coordinate, x2 is the second, y1 is the first y coordinate, y2 is the second.
(5-3)/(2-2)
2/0
This equation has an UNDEFINED SLOPE, as it is just a vertical line.
