WebAnswer (1 of 5): A square with area of 5^1/2 would have side lengths of 5^1/4. Given that circle is inscribed, the diameter of the circle, touches both sides of the square, meaning that the diameter is the same length as the square’s side length of 5^1/4. Circumference is pi*d or pi tines the di... WebThe formula for the area of a circle is πr 2. For this particular circle, the area is 81π, so 81π = πr 2. Divide both sides by π and we are left with r 2 =81. Take the square root of both sides to find r=9. The formula for the circumference of the circle is 2πr = 2π(9) = 18π. The correct answer is 18π.

WebBecause the area of an equilateral triangle is ¼ a²√3. Since a = r√3 also stated as a² = 3r². Substituting, πr² - ¾r²√3. Since r = 2, we get 4π - 3√3 = 7.370. Of course my way does require knowing that a² = 3r² for an inscribed equilateral triangle (though it isn't too hard to derive if you didn't know that) Comment.
