If by ' A 64 pi' you mean the Area. Then
A = 64pi
Since A = pi r^2 and 64 is 8^2
Then we can say r(radius)= 8
The circumference of a circle is
C = 2pir
Hence
C = 2 x 3.14 x 8
C = 16 x 3.14
C = 50.24 linear units.
The value for 'pi' at 3.14 is an approximation.
The circumference of any circle = diameter*pi or 2*pi*radius
I am not sure what you mean "A". In general, you can calculate the circumference of a circle:* By multiplying the diameter times pi, or
* By multiplying the radius times 2 times pi.
Area = 64pi implies that radius = 8 units So diameter = 2*rad = 16 units.
64pi (miles square)
Circumference = 2pi*r Circumference = 86pi
The area of a circle can be found with the formula (pi)r2. Since r = d/2, r would be 8in in this case. A = 64pi in2, or 201.1in2
circumference = 24.5
Area = 64pi implies that radius = 8 units So diameter = 2*rad = 16 units.
64pi
A = 64pi
64pi (miles square)
Area = 4*pi*42 = 64pi square units
Area of pizza: 64pi square inches.
The new volume is 76.566 cubic inches.
area = pi*r2 2r = d r = 8 inches area = pi*82 area = 64pi
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi
Surface area of the sphere: 4*pi*42 = 201.062 square inches rounded to 3 decimal places
A circumference is 4
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
