Answer:
V = (4/3)π(4)³ = four-thirds pi (4) cubed.
Step-by-step explanation:
The volume of a sphere is given by the equation ;
Volume; V = (4/3)πr³
Where r is radius.
Now, we are told that the radius has a value of; r = 4 in
Thus, plugging it into the volume equation, we have;
V = (4/3)π(4)³
Looking at the options given in the question, the correct answer is;
V = four-thirds pi (4) cubed
Using proportions, it is found that the same job will take Mrs. Squirrel 6 hours.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The times are given as follows:
- Mr. Pigeon: 30 minutes = Half an hour = 1/48 day.
The ratios are as follows:
Turtle/Squirrel = Squirrel/Pigeon.
Hence:
![\frac{3}{x} = \frac{x}{\frac{1}{48}}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%7D%20%3D%20%5Cfrac%7Bx%7D%7B%5Cfrac%7B1%7D%7B48%7D%7D)
![x^2 = \frac{3}{48}](https://tex.z-dn.net/?f=x%5E2%20%3D%20%5Cfrac%7B3%7D%7B48%7D)
![x^2 = \frac{1}{16}](https://tex.z-dn.net/?f=x%5E2%20%3D%20%5Cfrac%7B1%7D%7B16%7D)
![x = \sqrt{\frac{1}{16}}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B%5Cfrac%7B1%7D%7B16%7D%7D)
x = 1/4.
It takes 1/4 of a day for Mrs. Squirrel to do the job, hence 1/4 x 24 hours = 6 hours.

Answer:
94 press ups
Step-by-step explanation:
62 x 1.52 = 94.24
≈94
For example x^2=25
Without x the expression wouldn't exist, it allows you to calculate unknowns for example in a physics experiment using v=u+at
