Answer:
yes it is if we can write decimal numbers in the form of a fraction then it is a rational number
The volume of cone is 24
or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.
Step-by-step explanation:
The given is,
Formula for volume of cone, 
Where, B = 
Volume, 
From the given,
Radius, r = 3 centimeters
Height, h = 8 centimeters
volume, 



Volume of cone, V= 24
(volume in terms of
)
( or )
Volume, V = (24 × 3.14 ) ( ∵
=3.14 )
V = 75.398 cubic inches
Result:
The volume of cone is 24
or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.
Answer:

Step-by-step explanation:

Add 25 to both sides:


Square root both sides:
(Since a negative number multiplied by itself gives positive, there are two answers.)

Area of course also just a reminder Area is measured in square units such as square centimteres, square feet, square inches, etc
