How do you find radius squared

[From: ] [author: ] [Date: 12-05-13] [Hit: ]
so radius is 5/2 = 2.radius squared is the square of the radius, so radius squared is 2.5^2 =2.5*2.5 = 6.......
a 5"diameter cylinder that is 6.25 radius squared. how do you get 6.25?

-
radius is half the diameter, so radius is 5/2 = 2.5 inches
radius squared is the square of the radius, so radius squared is 2.5^2 =2.5*2.5 = 6.25 inches squared

The area of a square is side "squared ; that is 3 ft times 3 ft = 9 square feet

by definition of

but what isis the area of a circle ? O it is Not a square. the ancient Greeks figured it was:
Area = PI * R squared , written as Pi R^2 = Pi times R times R

read as Pi times R to the second power

pi is a number that can never be written only calculated to a "close number"
Pi = 3.141596..... to millions and millions of decimals

your Q makes no sense? what is the question?
if its diameter is 5 its radius is 2.5 and 2.5 * 2.5 = 6.25

the area would be 3.14159 * 6.25 = about 19 square inches, its volume would be area times height in inches

-
Radius squared = (diameter / 2)^2 = (5"/2)^2 = (2.5")^2 = 6.25 square inches
