What is the area of a circle if its diameter is 9 centimeters?
The formula for a circle's area is pi*radius*radius.The diameter is equal to two times the radius.D = 2*radiusSo, the radius is 4.5 cmArea = pi*radius*radius = 3.14159 * 4.5cm * 4.5cm = 63.617 cm2

A cone with a radius of 6 centimeters and a slant height of 9 centimeters will have a total surface area of approximately 282.74cm2
What is the area of a circle if the radius is 9 In?
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
If The exact area of a circle is 81pi square inches what are the radius and diameter of the circle explain?
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
