Danessa needs to compare the area of one large circle with a diameter of 8 to the total area of 2 smaller circles with a diameter
one-half that of the large circle.
Which statements about the areas are true? Select three options.
The area of the large circle is 16.
The area of one small circle is 47.
The area of one small circle will be one-half of the area of the large circle.
The total area of the two small circles will equal that of the large circle.
The total area of the two small circles will be one-half of the area of the large circle.

step-by-step explanation:

dong do iy iys a scram

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

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
