8:5

x = 15

Step-by-step explanation:

Ratio of areas is 64:25.

The ratio of lengths squared gives you the ratio of areas.

The ratio of lengths squared = 64:25

Ratio of lengths is 8:5

The ratio of 24:x equals the ratio 8:5 then

x = 24 * 5/8

x = 15

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

only 10/60 isn't equivalent

hope this : )
