Area of a Circle (A) = pi times the radius (r) squared
A = (pi) (r)2
Diameter of a Circle (d) = 2 times the radius (r)
d = 2r
First, find the r
Since the diameter (d) = 70 cm, then
70 cm = 2 r
(70 cm)/2 = r
r = 35 cm
Now that you have found the value of the radius (r),
you can plug in r for the equation for the area (A) of a circle:
A = (pi) (35 cm)2
A = (pi) 1225 cm2
At this point you can multiply 1225 cm2 by pi with a calculator to get
the value of 3848.45100065 which can be simplified to 3848.5 cm2

3,848.45 square meters.
What is the diameter of a circle if the circumference is 70 feet?
diameter = 70/pi
What is the area in square feet of a 70 foot circle?
The area of any circle is determined by the formula: A = πr2 where A is the area, π is "pi", the ratio of a circle's circumference to its diameter (approximately 3.1416), and r is the radius of a circle, or half its diameter. If your diameter is 70 feet, the radius is 35 feet. So, ... A = πr2 = (app) 3.1416 x 352 = (app) 3,848 square feet, or about 0.09 acres.
