Me find the area of two similar octagons

ANSWER

3:5

EXPLANATION

The given similar octagons have areas 9 m² and 25m² .

Let the scale factor of their side lengths be in the ratio:

m:n

We take square root of both sides to get;

We simplify the square root to get

Therefore the scale factor of their side lengths is 3:5

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
