If circle A has 4 times the radius of circle B how many times bigger is the area of circle A than circle B?
16
What is the area of a circle that is 16 meters in diameter?
Area of a Circle = Pi * radius squared Radius = Diameter / 2 So, Area = Pi * (16/2)^2 = Pi * 64 = 201.06 m^2 Measurement is in meters squared.
What is the area of a circle if the radius is 9m?
The area of a circle if the radius is 9m 254.5m2
What is the radius of a circle with the area of 36?
The radius of a circle with the area of 36 is 3.385
If the radius of a circle is doubled what happens to the area?
It quadruples. The area of a circle is Pi (about 3.14159) times the radius squared. So if you double the radius (say from 2m to 4m), you area will change from 4*Pi to 16*Pi (4 times what it was originally).
What is the area of a circle with a radius of 16 inches?
256 Pi. The area of a circle is equal to the radius square multiply by pi
What is the area of a circle using pi if radius is16cm?
A circle with a radius of 16 cm has an area of 804.25 square cm.
If the area of a circle is 16 pie what is the length of the radius of the circle?
4.
What is the area of a 16 foot circle?
Area of any circle is: pi times radius squared
What is the area of a circle if the radius is 4 cm?
Area of a circle = π*r2 =π*16 =16*pi cm2
What is the area of a 16 inch diameter circle?
Area = pi * radius * radius radius = diameter / 2 radius = 16/2 = 8 Area = 64 * pi Area 201.062 inches2
What is the area of a circle with the radius of 16?
804.25 square units.
What is the area of a circle with a radius of 4?
The area of a circle is pi times the square of the radius: A = πr2. For a circle of radius 4, this is π x 42 = π x 16 = 50.265 units squared.A circle with a radius of 4 units has an area of 50.27 square units.
What is the area of a circle with the diameter of 16 in?
Radius of a circle = 1/2 of the diameter.Area of a circle = (pi) x (radius)2For the diameter of 16 inches, radius = 8 inches, and area = (pi) (8)2 = 201.062 square inches (rounded)
How many times greater is the area of a circle with the radius of 10 than a circle with a radius of 8 centimeters?
25/16
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
What fraction of the area of a circle of radius 5 lies between concentric circles of radius 3 and 4?
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
