ur gonna have to find the multiples of 12 and 16the least common multiple will be ur answer.

multiples of 12 are : 12,24,36,48,60

multiples of 16 are : 16,32,48,64

the lcm of 12 and 16 is 48so he will go both hiking and swimming in 48 days

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
