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 area of a circle if the radius is 9m 254.5m2
The radius of a circle with the area of 36 is 3.385
It is not possible to have a circle with an area of 100 metres. Areas must be measured in square units, such as square metres. Assuming that the circle had an area of 100 sq metres, its radius would be 5.64 metres (to 2 dp).
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.
A circle with a radius of 50 mm has an area of 7853.98 square mm
Radius 10, area = 100 pi; radius 9, area = 81 pi
Use the equation: Area of Circle = pi * r^2 so... 100 pi = pi * r^2 The pi's cancel out. 100 = r^2 Square both sides to find the radius. square root(100) = r, the radius of the circle
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.
This is the area of a circle with a radius of 100 miles →area = π × radius² = π × (100 miles)² = 10,000π sq miles ≈ 31416 sq miles
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.
Using 3.14 as Pi the area of circle is: 314.0
