The area of a circle can be calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Given a radius of 100, the area of the circle would be A = π(100)^2 = 10000π square units. This simplifies to approximately 31415.9 square units.

A circle with a radius of 50 mm has an area of 7853.98 square mm
Knowing that the area of a circle is its radius squared times Pi, the area of a 10 ft radius circle is 100*Pi square ft, or about 314 square feet.
The area of a circle with a radius of 10 cm would be 100 times pi, or, rounded to the nearest hundreth, 314.15 cm2.
The formula for the area of a circle is A = πr^2, where A is the area and r is the radius of the circle. To find the radius from the diameter, you divide the diameter by 2. So, for a circle with a diameter of 100, the radius would be 50. Plugging this into the formula, the area would be A = π(50)^2 = 2500π square units.
The radius of a circle with the area of 36 is 3.385
