The area of a circle is 1 sq ft. What is the radius of the circle in inches?

Answer 1

Area = pi * radius^2

thus, radius^2 = area/pi

radius = square root of (area/pi)

In your example, area = 1 ft^2, so radius = sqrt(1/pi)

r = 0.56 feet, or 6.77 inches

Answer 2

components are in sq. gadgets --- occasion sq. inches, sq. ft, sq. meter, sq. yards, etc. Now only because of the fact its reported as sq. section does not propose the form of the section itself must be sq.. A around lot has a community, an oblong piece of paper has a community, etc. So what you could desire to be responsive to is the formulation to calculate the component of a circle. component of circle = Pi x radius x radius = Pi x radius^2 right here, pi isn't slightly pie yet somewhat a needed type (additionally reported as an irrational type, yet it is yet another lesson) it is comparable to the ratio of the circumference of the circle to its diameter or two times the radius. because it seems, Pi is greater or less equivalent to 3.1416..... it is going on consistently (surprisingly much, no person's found out the final digit yet). So getting returned on your question, the component of the circle with a radius of a million foot is then Pi x (a million) x (a million) = Pi = 3.1416.... sq. ft. nicely because you desire it in inches, you could convert your radius it is in ft to inches, a million foot = 12 inches section = Pi x 12 x 12 = Pi x a hundred and forty four = 452.4 sq. inches (I rounded off the digits)

Answer 3

it is 12 times the square root of 1 over PI = 6.77 inches

Answer 4

A = pi r^2
sqrt 1/3.14 = r
convert r to inches

Answer 5

A = rrR²
1² = 3,14*R²
1 : 3,14 = R²
R² = 0,3184713
R = 0,5643 ft = 6,7in²

Answer 6

Six inches I think , but it's been awhile since I had to take a Math class.

Answer 7

A= pi*r^2

r^2 = A/pi

|r| = (A/pi)^(1/2)

|r| = (1/pi)^(1/2)
