Pie X radius X radius or Pie X r2 ie circle with a radius of 3 ft. take 32 =9 * 3.14 = 28.26 ft2
r2*pie=circumference 9(9)*pie 81*pie 254
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
Area of a circle with radius r = pir2Area of the largest circle = Area of the smallest circle + Area of the shaded regionSince areas of the smallest circle and the shaded region are 9pi and 72pi, the Area, A, of the largest circle isA = 9pi + 72pi = 81pi, where r2 = 81.Thus, the radius of the largest circle is 9
The area of a circle with a radius of nine centimeters is: 254.5 cm2
Pie X radius X radius or Pie X r2 ie circle with a radius of 3 ft. take 32 =9 * 3.14 = 28.26 ft2
The formula for the area of a circle is pie r squared therefore if pie r squared = 254.5 r squared = 254.4 divided by pie = 81.009... r = square root of 81.009... = 9.000... = 9 ( correct to the nearest whole number) therefore radius of this circle is 9
r2*pie=circumference 9(9)*pie 81*pie 254
(pie)(diameter)=(circumference) (pie)(9)(2)=18(pie)=56.549
A circle with a radius of 9 feet has an area of 254.47 square feet.
Area of a circle with radius r = pir2Area of the largest circle = Area of the smallest circle + Area of the shaded regionSince areas of the smallest circle and the shaded region are 9pi and 72pi, the Area, A, of the largest circle isA = 9pi + 72pi = 81pi, where r2 = 81.Thus, the radius of the largest circle is 9
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
The area of a circle with a radius of nine centimeters is: 254.5 cm2
Area of a circle of radius r = πr2Area of circle of radius 9 In = π(9)2 = π x 81 , putting value of pi we get= 3.14159625 x 81 = 254.46 sq. In
A circle with a radius of 9 feet has an area of 254.47 square feet.
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches
The area is 254.47 in2
