Learn how to solve problems with tangent line. A tangent line to a circle is a line that touches the circle at exactly one point. The tangent line to a circle makes a right angle with the radius of the circle at the point of its...

This video explores five fun facts about circles.

In this video, the teacher explains the different parts of a circle and which ones require a formula to find. They go on to explain the formulas for circumference, area, length of an arc, and area of a sector. The teacher also provides...

👉 Learn how to find the volume and the surface area of a cylinder. A cylinder is a 3-dimensional object having two circular bases and a round surface joining the bases. The vertical distance between the circular bases of a cylinder is...

👉 Learn how to find the volume and the surface area of a cone. A cone is a 3-dimensional object having a circular base and round surface converging at a single point called its vertex (or apex). The vertical distance from the circular...

This Video Explains the formula related to Area, Circumferences, arc, sector of a circle

The video teaches basic terminologies and concepts related to circles, using a circular park as an example. It covers the definitions of a circle, radius, diameter, chord, secant, segment, arc, circumference, tangent, and sector. It also...

In this video viewers will learn that many natural and human objects are circle-shaped. Students will come to understand that the two basic dimensions of a circle are its circumference and its diameter. Using real life examples students...

Learn how to solve problems with tangent line. A tangent line to a circle is a line that touches the circle at exactly one point. The tangent line to a circle makes a right angle with the radius of the circle at the point of its...

This is a video about tangents in circles, explaining what they are, how they get their name, and their properties. The video also includes examples and proofs to help understand the concepts better.

The nugget explains the anatomy of human eye, its associated structures, chambers and fluids.

If you were alive 200 years ago you would have been given some very strange advice on how to avoid getting ill. You might have been told to carry sweet smelling flowers with you or avoid going to smelly places. This was because at that...

The video is a lecture presentation focused on physical quantities and measurements. The speaker begins by defining what a physical quantity is, and explains how different quantities like length, mass, and volume can be measured using...

It's time to learn about microorganisms! These are all the tiny little critters in the water, and the air, and in the ground, and inside you. We didn't even know they were there until a few hundred years ago, but once we started to learn...
