64pi (miles square)
The area of a circle whose diameter is 18 inches is: 254.5 square inches.
The area of a circle can be found with the formula (pi)r2. Since r = d/2, r would be 8in in this case. A = 64pi in2, or 201.1in2
A diameter is a line, and has no area.A circle whose diameter is 8.5 has an area of 56.745. (rounded)

64pi (miles square)
The diameter of a circle whose area is 200.96 is: 16
area = pi*r2 2r = d r = 8 inches area = pi*82 area = 64pi
The circumference of a circle whose area is 16 times the area of a circle whose diameter is 1.4m is: 17.6 cm
The area of a circle whose diameter is 200 meters is: 31,420 m2
The area of a circle whose diameter is 6 mm is: 28.27 mm2
The area of a circle whose diameter is 10 cm is: 78.54 cm2
The area of a circle whose diameter is 12 inches is: 113.1 square inches.
The area of a circle whose diameter is 18 inches is: 254.5 square inches.
64pi
The area of a circle can be found with the formula (pi)r2. Since r = d/2, r would be 8in in this case. A = 64pi in2, or 201.1in2
A = 64pi
