If you need the radius, the diameter, or the circumference, use the formula A = pi x r2 to calculate the radius. The diameter is twice the radius; the circumference is radius x 2 x pi.

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 is the area of a circle whose circumference is 8 pi?
Using 3.14 as Pi the area of circle is: 0
What is the area of a circle with the radius of 4 in to the nearest tenth show work?
Area of a circle = (pi) x (radius)2 = (pi) x (4)2 = 16 pi = 50.3 in2 (rounded)
How is pi in relation to a circle?
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
How do you get an area for a circle?
Area of a circle = Pi * radius2
A circle has a radius of 16 what is the area of the circle?
Area = pi*16*16 square units
What is the area of a circle whose circumference is 100?
Using 3.14 as Pi the area of circle is: 0
If the area of a circle is 16pi what is the circumference of the circle?
area = {pi}r2 = 16{pi} --> r2 = 16 --> r = 4 circumference = 2{pi}r = 2{pi}4 = 8{pi}
The radius of a circle is x-4 what is the area of the circle?
Area = pi R2 = (x2 - 8x + 16) pi
What is the area of a circle a diameter of 16 in?
Using 3.14 as Pi the area of circle is: 200.96
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 that has a circumference of 16 PI?
The area of a circle that has a circumference of 16pi is: 201.1 units2
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 will be the area of the circle if the diameter of the circle is 16ft?
The diameter = 2*r where r is the radius of the circle. So 16 = 2r. Therefore the radius = 16/2 = 8. The area of a circle = Pi*r^2 = Pi*(8)^2 = 64*Pi.
What is the area of a circle with a 4 in radius?
Using 3.14 as Pi the area of circle is: 50.24
What is the area of a circle radius of 4 inches?
To find the area, the formula is: pi*r2.Plug in the information: pi*(4)2.Solve: pi*16
