Sphere A has a diameter of 12 and is dilated by a scale factor of one half to create sphere B. What is the ratio of the volume of sphere A to sphere B? 2:1 8:1 12:6 144:36

VA/VB = 8

Step-by-step explanation:

You have a sphere A with diameter 12, that is, radius 6, which can be written as follow:

            (1)

The sphere A is dilated by a scale factor of one half to sphere B. Then, you have:

      (2)

From the results of equation (2) and (1) you can calculate the ratio VA/VB:

The ratio of the volumes of both sphere A and B is 8

correct answer:

i^31 = -i

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
