3 * pi meters
Area of a triangle = 0.5*base*height. In this case, area = 0.5*3*5 = 7.5 metre2.
7.0686 square feet for a 3-foot diameter circle.
Area = pi*7.52 = 176.715 square cm rounded to 3 dp
3 square metres
A cylinder that has a diameter of 10 meters and a height of 3 meters has a surface area of 251.33m2
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.
Area of a circle with diameter 'D' meters = (Pi x D squared) / 4 Square meters Therefore, Area=(3.14x3x3)/4=7.065 Sqm.
Area = pi*152 = 706.858 square meters to 3 dp
It is: 10.093 meters rounded to 3 decimal places
Area = pi*12.252 = 1847.453 square meters rounded to 3 dp
Area = pi*42 = 50.265 square meters to 3 d.p.
Area = pi*102 = 314.159 square meters to 3 decimal places
Area = pi*502 = 7853.982 square meters rounded to 3 decimal places
Area = pi*9 squared = 254.469 square meters to 3 decimal places
The circumference of a circle with a diameter of 3 meters is: 9.42 meters (diameter x Pi = circumference).
The diameter of a circle with a 3-meter circumference is: 0.9549 meters.
