What is the area of a circle with a radius of 9 centimeters?
The area of a circle with a radius of nine centimeters is: 254.5 cm2
What is the radius of a circle 18feet across?
9 feet.
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 a 6 dia circle?
Area = pi * radius^2. radius = diameter / 2, so radius of this circle is 3.Area = 9 * pi (take your favorite value of pi: 3.1416....)
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 area of a circle if r9ft?
A circle with a radius of 9 feet has an area of 254.47 square feet.
What is the radius of a circle whose area is 254.47 square feet?
The radius is 9 feet.
Circle A has radius 4 feet circle B has radius 9 feet What is the ratio of the area of circle A to the area of circle B?
Area(A)/ Area(B) = pi*rA2/pi*rB2 = rA2/rB2 = 16/81
The area of a circle is 81 pi square feet What is the radius?
The area is 9 feet. You find the square root of 81 which is 9. I want circumference, not area.
What is the radius of a 9ft by 9 ft circle?
Since your circle has a diameter of 9 feet (the definition of a "9 by 9" circle), the radius is half of that distance. In this case, your radius is 4.5 feet or 54 inches.
What is the area of a circle if it has a diameter which is 18 feet long?
The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)
What is the area of a circle with a radius of 9 in?
Area of circle: pi times 9 squared = 254.469 square feet rounded to 3 decimal places
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 area of a circle with a radius of 9 centimeters?
The area of a circle with a radius of nine centimeters is: 254.5 cm2
How many sq feet in a 9' circle?
You should say if the 9 feet is a radius, diameter or circumference.....if radius then 254.47 feet
What is the radius of a 9' circle?
r = 4.5 feet
