Answer:
4/3π(0.973r³)
Step-by-step explanation:
Volume of a sphere = 4/3πr³
Given the radius of dodge ball rd = r
radius of tennis ball rt = 0.3r
Taking their difference
Volume difference = 4/3πrd³ - 4/3πrt³
Volume difference = 4/3π(r)³ - 4/3π(0.3r)³
Volume difference = 4/3π(r³ - 0.027r³)
Volume difference = 4/3π(0.973r³)
Hence the differmce in volume is 4/3π(0.973r³)
First, draw the number line and assign the values of the real numbers that correspond (See the figure attached).
Now, let's represent the mixed numbers given in the problem.
Let's start with 8 2/5: This mixed number is located between 8 and 9. The numerator 2 of the fractional part, tells us how far from 8 it will be located and the denominator 5 indicates how many parts we must divide the space between these two numbers (8 and 9).
Now, to plot 2 3/4 on the number line, we have to follow the same proccedure: It is located between the numbers 2 and 3. The numerator 3 of the fractional part, tells us how far from 2 it will be located and the denominator 4 indicates how many parts we must divide the space between 2 and 3.
Answer:
566.4
Step-by-step explanation:
do multipilication
X = 6, y = 8, z = 3

3(8) + (6)² = 24 + 36 = 60

= 20
