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
What is the surface area of a cone with a radius of 6 centimeters and a slant height of 9 centimeters?
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
What is the area of the shaded region of a circle if the diameter is 18 centimeters and the area shaded is 270?
To find the area of the shaded region, you first need to calculate the area of the entire circle. The radius of the circle is half the diameter, so it is 9 centimeters. The area of the circle can be calculated using the formula ( A = \pi r^2 ), which gives approximately ( 254.47 ) square centimeters. Since the shaded area is given as 270 square centimeters, this indicates that the shaded region exceeds the area of the circle, suggesting a possible error in the given dimensions or a misunderstanding of the problem.
If radius of a circle is 9 centimeters what would be the circumference?
If radius of a circle is 9 centimeters the circumference would be: 56.55 cm (r x 2 x Pi = circumference).
What is the area of a circle if its diameter is 9 centimeters?

What is the area of a circle with a radius of 9 ft?
A circle with a radius of 9 feet has an area of 254.47 square feet.
What is the circumference of a circle that the radius is 9 centimeters?
circumference = 2*pi*9
What happen to the area of circle when the radius is tripled?
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
What is the surface area of a cone with a radius of 6 centimeters and a slant height of 9 centimeters?
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
