CBSE Class 10 - Area and Circumference of a Circle Videos
This video explains a case study question based on area of concentric circles
- A square with perimeter p cm has more area than a circle with circumference p cm. State true or false with explanation
- if area of circle numricle double its perimeter find the radius of circle 4units
- If a truck covers 2.2 km and each wheel makes 350 complete revolution.Find the radius of the wheel
- the forewheel of tractor makes 120 revolution more than the rear wheel in going 720m. if the diameter of the forewheel is doubled and the diameter of the rear wheel in increased by half times the present diameter then the forewheel makes 20 revolution more than the rear wheel in going the same distance find the circumference of each wheel
- Hello Sir, Please clarify my doubt 1) A wire is in the form of a square of side121cm.It is cut and made into the shape of a circle.Find the diameter of the circle. 2) a wire is in the form of a triangle of sides 28cm,26cm and 30cm.The wire is cut and made into a circle.Will the area of the circle be the same as that of the triangle? Thank You.
