# A rectangle is inscribed in a semicircle of radius 2

- 6. A norman window has the shape of a rectangle surmounted by a semicircle. (Thus the diameter of the semicircle is equal to the width of the rectangle.) If the perimeter of the window is 30 ft, find the dimensions of the window so that the greatest possible amount of light is admitted. 7. A piece of wire 30m long is cut into two pieces.

A rectangle is to be inscribed in a semicircle of radius 2. What is the largest area the rectangle can have and what are its dimensions? 1st, all radii of the same circle are equal. 2nd, a semicircle divides into 2 equal quarter circles; when doing so equal isosceles right triangles are formed.Let ABCD be the rectangle inscribed in a semicircle of radius 1 unit such that the vertices A and B lie on the diameter. Let AB = DC = x and BC = AD = y. ∴ Area of circle = πr 2. If radius is tripled, then new radius will be 3r. ∴ Area of new circle = π(3r) 2 = 9π 2. 9 times of original. Hence, the area of a circle becomes 9 times to the original area. Question 37. The area of a semicircle of radius 4r is A. 8πr 2 B. 4πr 2 C. 12πr 2 D. 2πr 2.

I think that the circle must have a diameter of 4 units, otherwise it would not fit inside the rectangle. I drew a diagram below with one circle having radius 2 units (diameter 4 units) and the other having an unknown radius of x units. The right triangle CPD has |CP| = 5 - 2 - x, |PD| = 6 - 2 - x and |DC| = x + 2 The theorem of Pythagoras ... Angle in a Semicircle (Thales' Theorem) An angle inscribed across a circle's diameter is always a right angle: (The end points are either end of a circle's diameter, the apex point can be anywhere on the circumference.) Thus, the perimeter of the semicircle is comprised of the diameter AB and of arc AB. If you denote the radius of C as r, then the diameter is 2r, and the arc is half of the circumference: 2πr/2. Thus, the perimeter of the semicircle is 2r + 2πr/2 = 4+4π A Incorrect. 5) A geometry student wants to draw a rectangle inscribed in a semicircle of radius 7.
