A CIRCLE HAS AN AREA OF 50 SGUARE FEET.WHAT IS THE APPROXIMATE DIAMETER OF THE CIRCLE?ROUND TO THE NEAREST WHOLE FOOT.
area= PI (diameter/2)^2
diameter^2=4*area/PI
diameter= 2 sqrt (area/pi)
I have no clue
To find the approximate diameter of a circle, you need to use the formula for the area of a circle. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius of the circle.
In this case, we are given the area, which is 50 square feet. We can set up the equation as follows:
50 = πr^2
To solve for r, you need to divide both sides of the equation by π, and then take the square root of both sides:
r^2 = 50/π
r ≈ √(50/π)
Now, to find the diameter, you need to multiply the radius by 2:
d ≈ 2 * √(50/π)
To round to the nearest whole foot, you can use the approximate value of π as 3.14:
d ≈ 2 * √(50/3.14)
Now, you can calculate the approximate diameter by plugging in the values:
d ≈ 2 * √(50/3.14)
≈ 2 * √(15.92)
≈ 2 * 3.99
≈ 7.98
Rounding to the nearest whole foot, the approximate diameter of the circle is 8 feet.
