If you have a circle with an area of approximately 45 square feet, what is a good estimation for the radius of the circle?
question 1: what is the formula for finding the area of a circle?
options: C=2πr, A=2πr^3, A=πr^2
question 2: what would be the first step in solving for the radius
options: square each side of the equation, divide 2 on each side of the equation, multiply by π on each side of the equation, divide π on each side of the equation, subtract π from each side of the equation, take the square root of each side of the equation
question 3: what would be the second step in solving for the radius
options: square each side of the equation, divide 2 on each side of the equation, multiply by π on each side of the equation, divide π on each side of the equation, subtract π from each side of the equation, take the square root of each side of the equation
question 4: the approximate radius would be out...
options: 7.16 feet, 2.1 feet, 3.8 feet
Question 1: A=πr^2
Question 2: take the square root of each side of the equation
Question 3: divide π on each side of the equation
Question 4: 3.8 feet
