Area = 1/4*Pi*d2 = 0.25*3.14*82 = about 50.24m2
The radius of the circle is half of the diameter, so it is 4 meters. To find the area of the circle, we can use the formula A = πr^2. Substituting the value of the radius, the area of the circle is therefore A = 3.14 * (4)^2 = 3.14 * 16 = 50.24 square meters.
314 ft2
A circle with a radius of 10 meters has an area of 314 square meters.
pi x square of radius gives area. 3.14 x 100 = 314 sqft.
314 sqmm
Area of circle is pi r^2, in this case approx 314 sq cm (3.14 x 10 x 10). For your semi-circle, half of this ie 157 sq cm
314 ft2
314 ft2
A circle with a radius of 10 meters has an area of 314 square meters.
A circle with a radius of 10 meters has an area of 314 square meters.
The diameter of a circle whose circumference is 314 is about 1 (99.95).
Diameter = 314/pi feet
100pi, or approximately 314.
The diameter of the circle works out as 20 units to the nearest whole number
Using pi as 3.14 it works out that the diameter is 20 cm
9.9975
100*pi≈314 feet
pi x square of radius gives area. 3.14 x 100 = 314 sqft.
