C. 2:3 because the original ratio is 12:18, but to complete this ratio you would need to simplify the ratio to 2:3.
Answer:
The answer is 3/5 x 6/1 = 18/5
Step-by-step explanation:
First you want to turn the whole number into a fraction all you have to do is put a 1 as the numerator the numerator is the top number then multiply 3/5 and 6/1 you have to keep the first fraction the same switch the division symbol to multiplication symbol and flip 1/6 to 6/1 and when you multiply 6/1 and 3/5 you will get 18/5.

The right answer is Nine.
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!
