# How does footage you take on a circle lens camera turn into square or rectagle when you watch it on your TV?

Good question!

The image transmitted by the lens is actually circular, but it passes through a rectangular opening just before the film plane. This creates a rectangular image on the film because part of what the lens is transmitting is blocked. You are never reminded of this since the entire "previewing" system is constructed to show you what you will get, not what the lens actually "sees".

### What is the square footage of a 6 foot flat circle?

To find the Square Footage of a 6 foot circle (flat), we must use the equation for Circle Area: Circle Area = pi × r2 Since we know that Diameter = 6 feet we Therefore know that Radius = Diameter/2 = 3 feet = r So, Since, the constant pi = 3.14159 (approximate), we now have all the numbers to put into our Circle Area equation: Square Footage of a 6 foot flat Circle =… Read More

### How do you compute the square footage inside a circle?

Multiply the diameter by 3.1415 NO - ignore that! Diameter x pi (3.1416) is the circumference, the distance around a circle. Square footage is area, so the correct formula is Area = 3.1416 times radius squared. The radius would be measured in feet. Read More

### What is the square footage of a circle with a diameter of 45 feet?

Instead of "square footage", those who are comfortable with their math almost always call it "area". After all, it could be square inches, square meters, or acres. Each of those would still be 'area', even though none of them is 'square footage'. Area of a circle = (pi) x (radius)2 Radius = 1/2 of the diameter Area of your circle = (pi) x (22.5)2 = 506.25 (pi) = 1,590.43 square feet (rounded) Read More
