A small silver dollar pancake served at a restaurant has a circumference of 2 inches. A regular pancake has a circumference of 4 inches. Is the area of the regular pancake twice the area of the silver dollar pancake? Explain.

C=(2)(pi)(radius)

A=(pi)(radius)^2

Area of small silver dollar pancake=4pi

Area of regular pancake=16pi

16pi/4pi=4 times bigger than silver dollar pancake

NO, because in order to find the area of a circle you need to multiply pi with radius squared.

A=(pi)(radius)^2

Area of small silver dollar pancake=4pi

Area of regular pancake=16pi

16pi/4pi=4 times bigger than silver dollar pancake

NO, because in order to find the area of a circle you need to multiply pi with radius squared.

The side lengths of a square was dilated by the scale factor of 4/5. The new area of the square is 64 cm2. Find the original side lengths of the square.

Solve for side

a = 8 cm

A Area 64 cm^2

Using the formula

A = a^2

a =

a = 8 cm

A Area 64 cm^2

Using the formula

A = a^2

a =

Answer:

3/5

Step-by-step explanation:

We are to find the similarity ratio of a cube with volume to a cube with volume .

We know the formula for the ratio of two cubes:

where is the similarity ratio of the two cubes.

Substituting the given values in the formula to find :

Therefore, the similarity ratio of the two cubes is 3/5.

Answer:

The similitary ratio is 3:5

Step-by-step explanation:

To answer this question let's call:

to volume 1.

Let's call:

to volume 2

The relation k of simiiltud between both volumes we find dividing between
