Answer:
The volume of the softball is 6.6 times the volume of the tennis ball
Step-by-step explanation:
we know that
The volume of a sphere is equal to
step 1
Find the volume of the softball
we have
substitute
step 2
Find the volume of the tennis ball
we have
substitute
step 3
Divide the volume of the softball by the volume of the tennis ball
therefore
The volume of the softball is 6.6 times the volume of the tennis ball
<em>Alternative Method</em>
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
The scale factor is equal to the ratio of its radius
therefore
The scale factor elevated to the cube is
therefore
The volume of the softball is 6.6 times the volume of the tennis ball

Answer:
Step-by-step explanation:
Given:
Parallelogram P is dilated to form parallelogram P'.
The side of P which is = 10 units corresponds 20 units in P'.
The side of P which is given as =(x+3) units corresponds 8 units in P'.
To find the value of 
.
Solution:
The scalar factor of dilation from P to P' can be given as the ratio of the corresponding sides of the parallelograms.
The scalar factor :
⇒ 
⇒ 
⇒ 2
This means the sides of the parallelogram P' is twice the sides of the parallelogram P.
The side of P which is given as =(x+3) units corresponds 8 units in P'.
Using the scalar factor the equation to solve for can be given as:
⇒ 
Solving for .
Using distribution:
⇒ 
Subtracting both sides by 6.
⇒ 
⇒ 
Dividing both sides by 2.
⇒ 
∴ (Answer)
