471 cm

Step-by-step explanation:

Surface Area of Cylinder = 2πrh + 2πr^2

Since we are only finding the surface area on the outside of the cylinder, it’s just 2πrh

3.14 * 2 = 6.28

6.28 * 3 = 18.84

18.84 * 25 = 471

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
