What else can I help you with?
Fionna has 20 feet to put around a garden.what is the greatest area for the garden that she can make?
A square of side 5 would have an area of 25 sqft, but a circle of circumference 20 ft would have a bigger area: circumference = 2 x pi x r = 20 so r = 10/pi. Area = pi x r x r = pi x 10/pi x 10/pi which = 100 pi /pi x pi ie 100/pi which is about 31.8 sq ft.
What is bigger pi or googol?
Googol is a greater number than pi.
How many times bigger than the 5 circle in the 10 circle?
if you double the radius (or diameter) , you get four times the area. area of a circle = pi * radius squared
What you the relationship of pi and area?
The area of a circle is pi times the square of the radius. Pi has no relationship with the area of a polygon.
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
What is the difference between the areas of a circular target region with a radius of 5 meters and a target region with a radius of 7 meters?
The area of the 5 metre target is 25*pi metres2 whereas the bigger target has an area of 49*pi metres2. The difference is 24*pi = 75.4 sq metres.
What is the area of a circle you the circumference is 12 pi ft?
Circumference = 2 * pi * radius 12 pi ft = 2 pi radius radius of the circle = 6 ft Area = pi *radius2 Area = pi (6)2 Area = 36 pi ft2
Finding the diameter if given the circumference and area?
Circumference = pi*d Area = pi*d2/4 So 4*area = pi*d2 4*area/Circumference = pi*d2/(pi*d) = d
How do you find the circumference of a circle if you have the area and nothing else?
Area = (pi) x (Radius)2Radius = sqrt(area/pi)Circumference = (2 pi) x (Radius) = (2 pi) x sqrt(area/pi)Circumference = 2 x sqrt(pi x area)
Is it possible to have the surface area of a cylinder less than its radius?
Because the minimum surface area is greater than 2*pi*radius^2, we can set up an inequality: radius > 2*pi*radius^2 This is because we want the radius to be bigger than the surface area. When we solve the inequality, we find that 0<radius<0.15915494 (or 1/(2*pi).
What is the area of the area of a 16 diameter in tems of pi?
area = pi*8 squared
Formula of area of circle?
Area= pi times the radius squared or A=Pi(R)^2
