3 days ago · Let the centre of the circle be C’, the point of intersection of the line CB with the circle be T. Also, let the radius of the semicircle be R and that of the circle be r. Now use the required construction and properties of the geometrical figures to find a relation between r and R.
3 days ago · Now simplify the above equation we have, Now take square root on both sides we have, Now substitute this value in equation (3) we have, Hence x = y = r 2–√ = r 2 thus it forms a square with maximum area. So the rectangle of maximum area inscribed in a circle is a square.
3 days ago · Hint: Here, we will apply the concept of circumference and area calculation of circle as well as percentage manipulation in their formula. There is one term common in the formula of circumference and area and i.e. value of radius, so we will use the first condition of the question for finding the new value of radius.
3 days ago · A circle is inscribed in an equilateral triangle ABC with side 12 cm, touching its sides. Find the radius of the inscribed circle and the area of the shaded part.\n \n \n \n \n .
5 days ago · We can calculate the diameter by multiplying the radius by 2: d = r × 2. If the circumference is known: The diameter can also be calculated using the circumference: d = c / π. If the area is known: The formula to calculate the diameter from the area of a circle is: d = 2 × √(a / π)
3 days ago · Simplifying the calculations, we get, So, the area of an equilateral triangle inscribed in a circle of radius 10cm 10 c m is 75 3–√ cm2 75 3 c m 2 . So, the correct answer is “ 75 3–√ cm2 75 3 c m 2 ”. Note: In the above problem, the side of the equilateral triangle can be found in various ways.
