Cylinders a and b are similar solids. the base of cylinder a has a circumference of 47 units. the base of cylinder b has an
area of 9. units
the dimensions of cylinder a are multiplied by what factor to produce the corresponding dimensions of cylinder b?

Cylinders A and B are similar solids. The base of cylinder A has a circumference of 4π units. The base of cylinder B has an area of 9π units.

The dimensions of cylinder A are multiplied by what factor to produce the corresponding dimensions of cylinder B?

Dimensions of cylinder A are multiplied by  to produce the corresponding dimensions of cylinder B

Cylinders A and B are similar solids.

The base of cylinder A has a circumference of units

The base of cylinder B has an area of units

Let "x" be the required factor

From given question,

Dimensions of cylinder A are multiplied by what factor to produce the corresponding dimensions of cylinder B

Therefore, we can say,

The circumference of base of cylinder (circle ) is given as:

Where "r" is the radius of circle

Given that  base of cylinder A has a circumference of units

Therefore,

Thus the dimension of cylinder A is radius = 2 units

The area of base of cylinder (circle) is given as:

Given that,  the base of cylinder B has an area of units

Therefore,

Thus the dimension of cylinder B is radius = 3 units

Thus dimensions of cylinder A are multiplied by  to produce the corresponding dimensions of cylinder B

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
