Scale Factor As a word problem
A playground is 15 cm wide. After dilation, it is 150 cm wide. What is the scale factor of the dilation?

10

My Logic:

if im correct the scale playground is 15cm wide while the real playground is 150 cm wide. That means that the scale playground is 1/10 of the real one or 1/10 scale.

Hope the helps!

4*15=60

60+10=

70

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
