The circle of Willis is a continuous loop of arteries in the brain that provides collateral circulation. When you turn your head from side-to-side or up and down, the arteries in your neck stretch and flex. In the process, they may become compressed, which restricts blood flow.

Solved Examples Frequently Asked Questions What is the definition of a semicircle? When a line passing through the center touches the circle, this line segment which is formed is called the diameter. The diameter cuts the circle into identical halves. This plane figure thus formed is called a semicircle. The area of a semicircle

Determine the radius of your circle. For example, let's suppose it's 7 cm. Input the radius in the calculator, and you'll know the circle's circumference. The result should be 43.982 cm. To double-check your result, enter the radius in the circle perimeter formula: p = 2 × π × (7 cm) = 43.982 cm.

That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units. The area of a circle of radius r units is A = π r 2 . Substitute r = 4 in the formula. A = π ( 4) 2 = 16 π ≈ 50.24. Therefore, the area of the inscribe circle is about 50.24 square units.

If two tangents inclined at an angle 60 0 are drawn to a circle of radius 3cm, then length of each tangent is equal to A 233cm B 6cm C 3cm D 3 3cm Medium Solution Verified by Toppr Correct option is D) Was this answer helpful? 0 0 Similar questions

If the perimeter of a circle is equal to that of square, then the ratio of their areas is: (A) 22: 7 (B) 14: 11 (C) 7: 22 (D) 11: 14 Solution The correct option is B: 14: 11 Let the radius of the circle be r and side of square be a. According to the given condition, The perimeter of a circle = Perimeter of a square [Given] 2πr= 4a ⇒ a= πr 2 ………(i)

The convention is that you have 360 degrees in a circle. So let me explain that. So if that's the center of the circle, and if we make this ray our starting point or one side of our angle, if you go all the way around the circle, that represents 360 degrees. And the notation is 360, and then this little superscript circle represents degrees.

The radius of a circle from the area: if you know the area A, the radius is r = √ (A / π). The radius of a circle from circumference: if you know the circumference c, the radius is r = c / (2 * π). The radius of a circle from diameter: if you know the diameter d, the radius is r = d / 2.
