Children must learn math because it is a fundamental skill as well as important for daily life. Children learn about numbers, patterns, and relationships in math, all of which are significant ideas that they will come across in their daily lives. Children can learn math while also developing t...
The circumference of a circular lake is 30(km). Peter and Jane begin to cycle from the same point around the lake in opposite directions. Peter's speed is 250()/(min )\;, but he rests for 5 minutes after every 55 minutes of cycling. Jane's speed is 200()/(min )\;, but he ...

Chapter 19 – Mensuration I contains topics related to the circumference of a circle and the area of a circle. We, at BYJU’S, have prepared the solutions with detailed descriptions. Students can score full marks in the Maths exam by practising Frank Solutions for Class 10 Maths. ...
Mathematics deals with pure numbers: 1, 2, 3, fractions and more exotic numbers like π. Since π depends on lengths, we might think its value depends on our units. But it is the ratio of the circumference of a circle to its diameter and, as long as both are measured in the same ...
On top of topics covered from Primary 3 to Primary 5, with the introduction of new topics such as Algebra and Data analysis, students will also learn to find unknown angles of a parallelogram, the area and circumference of a circle, as well as calculate the perimeter of composite figures ...
The traditionally ‘higher’ surface area and volume work, such as spheres, cones and pyramids, also comes up infrequently, so it might be advisable to skim this in favour of spending more time on, for example, problem-solving using circumference and area of a circle. Read more: Pythagoras ...
