The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.
If a circle's area is 3.14 (Pi), its radius is: about 1.
Since area of a circle = πr^2, a circle with r=1 would have an area of π.
the area of the circle will be 1/4 of its original area
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
A circle with a radius of 1 unit has an area of 3.14 square units.
The area equals to pi: 3.141592654.....
The area of a circle is pi times (radius squared) Thus if radius is one inch then area is (pi) times (1) times (1) = pi = 3.1416 inches squared
pi or approximately 3.1415926535
If a circle's area is 3.14 (Pi), its radius is: about 1.
The area of a circle is {pi} x radius2. 12 = 1, so: a circle of radius 1 unit has an area of exactly pi units2
The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height
a circumference is a point in which two lines meet and the area is=pie R
No, the radius of a circle is always 1/2 of the diameter.
a=pi times r squared so pi or 3.1415926535898...
The area of Circle S can be found by using the area formula for circles. The area of a circle is pi times the radius squared. So, the area of Circle S with a 1 inch radius is Pi inches squared.
If the radius is 1, the diameter is 2, and the circumference is about 6.28. Since the area of a circle is πr^2, a circle with r=1 would have an area of π.
