How many square inches in a 5 foot diameter circle?
The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
Find the square inches for 12 inches in diameter?
The formula for finding the Area (square inches) of a circle is A = Pi x R-squared where Pi is 3.1416 and R is the Radius. Radius is one-half of the Diameter, so one-half of 12 is 6. Now, using the formula, do the math: A = 3.1416 x (6 x 6) = 3.1416 x 36 = 113.0976 square inches.
What is the area of a circle with a diameter of 16 in?
201 square inches. Area is calculated as the value pi times the square of the circle's radius; pi being approximately 3.1416 and the radius being half the diameter. So in this case, area A = pi X 8 X 8 = 3.1416 X 64 = 201 square inches (approx.)

How much would 1 psi be if it was spreaded over an area of 0.5 Sq Ft?
0.5 Sq Ft is one half of a square foot. A square foot is an area 1 foot long by one foot wide. A square foot can also be described in inches instead, so the area of one square foot is 12 inches long by 12 inches wide, or 144 square inches. 0.5 Sq Ft is half a square foot, and is equal to 144 square inches multiplied by 0.5, or one half. So half a square foot equals 72 square inches. 1 psi is one pound per square inch. If you spread 1 psi over an area of 72 square inches, you divide the pressure quantity by the area quantity: 1 psi divided by 72 square inches = 1/72 psi, or 0.0139psi.
