The area of a circle whose diameter is 200 meters is: 31,420 m2
154 cm2
Area = pi*r2r = Diameter/2r = 6.5 meters/2= 3.25 meters--------------------------now,Area = pi(3.25 meters)2= 33 m2======
A circle with a radius of 14 meters has an area of 615.75 square meters.
615.752 m2
Lateral area is 188.5 m2
Diameter being 22 meters, the area is 380.12 meters
The diameter of a circle whose area is 200.96 is: 16
The area of a circle with 6 meters diameter is 9xpi square meters. The area of circles with 4 meters diameter and 2 meters diameter are 4xpi and 1xpi square meters respectively. The combined area is 5xpi square meters. Thus the area 6 diameter circle exceeds the combined area by (9-5)xpi= 4xpi square meters. Substituting the value of pi as 3. 14, the exceeding area is 12. 56 square meters.
If the diameter of a circle is 37.3 meters its area is: 1,093 m2
The area is 110637.523 sqm.
The circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm
