7850 sq ft. Formula is pi x R squared. Diameter of 100 means Radius (r) is 50. 50 squared (multiplied by itself) is 25000. Multiply THAT by the value of pi- or 3.14, and you get 7850 sq ft.
The area of a circle = (pi) x radius squared radius = 1/2 diameter 3.14 x 5 feet squared 3.14 x 25 = 78.5 square feet
Area = pi R2 = 100 pi = 314.16 square feet (rounded)
The diameter of a circle whose circumference is 314 is about 1 (99.95).
It is 100 units.
The formula for the area (A) of a circle is A = πr2. If the area is 100π then 100π = πr2 : 100 = r2 : r = √100 = 10. The radius is of length 10 units.
I do not know about a circle with an area of 100 nmm3.A circle with an area of 100 mm2 has a diameter of 11.28 mm.
Assuming that a 100 ft circle is one with a diameter of 100 ft (ie radius of 50 feet), area = pi*502 = 1963.5 sq feet
For a circle with a diameter of 100 cm, the area is ≈ 9,503.32 cm2
100 feet.
Oh, dude, you're hitting me with some math now? Alright, so the circumference of a circle is just pi times the diameter. So, if the diameter is 100 feet, the circumference would be 100π feet. But like, who really measures things in terms of pi? Just round it to like 314 feet and call it a day.
100. The radius is 1/2 of the diameter.
Use the standard formula to calculate the area of the circle, then you can compare with the area given for the triangle. Note 1: The formula for a circle is: area = pi x radius squared Note 2: The radius is half the diameter
The question does not make any sense. A diameter is a measure which is applicable for a circle. However, a circle x a circle does not make any real shape.
A circle with a radius of 50 mm has an area of 7853.98 square mm
Area = pi*502 square cm
Area of a circle = (pi) (radius)2Radius = 1/2 of diameterArea = (pi) (10)2 = 100 pi = 314.16 square feet (rounded)
The central circle of stones is about 30 to 33 meters (100 feet) in diameter, and is part of a larger area about 110 meters (360 feet) across.
