Diameter = 7.8115 cm
It is: 16*pi square cm
Area of a circle = pi multiplied by (radius squared)Pi is approximately 3.141 so do r x r x 3.141
3848.451000 mm2 > 38.48451 cm 2
A 7-by-9 grid has an area of 63 square units.
The 'best' estimate of the area of a circle with a radius of 7.62 meters is: 182.414692 m2
Count the number of little grid-blocks inside the shape.
count squares completely inside the circle count squares partially in the circle but divide those by 2 add both parts above.
Diameter = 7.8115 cm
area of a circle is pi x radius^2 so... pi x 4^2 = about 50 cm
