the length of the dog's leash is 12 feet

Step-by-step explanation:

the dog's leash is the radius of circle

in which the dog plays

and the area is given =

area of circle =

so,

=》

=》hence r = 12 feet

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
