Now in simple language we have to find the circumference of a circle and then multiply it by 5 because he covered 5 rounds. To find that we have to apply a formula- 2Πr/ 2×22/7×r Now to find the radius of the circle we have to divide the diameter by two which is 12÷2=6 A/Q =2×22/7×6 =264/7 =37.71 =37.71×5 =188.55cm Therefore, he covered 188.55cm in total. Tips: These types of sum will become easier for you when you will learn the formulas.

Becoming a vegetarian has many benefits - for you and the environment.whether you're interested in animal welfare, avoiding to use of excess environmental resources,or simply can't afford to keep meat in your diet, there are plenty of reasons for choosing to become a vegetarian. Although many dieticians once believed a plant - based diet lacked sufficient nutrition, it has been found over the last few years that a vegetarian diet is nutrition- dense and can be aid in protecting against some chronic illnesses, including heart disease, cancer and type 2 diabetes. Vegetarian are likely to have lower bad cholesterol,blood pressure and body mass index (BMI). Besides benefiting your health, a vegetarian diet also postively impact the environment. My opponent say that vegetarian diet are devoid of the proteins and fats. I totally disagree and say that there are nuts,soya and milk products that contain protein and that is sufficient for our body. With all my points favouring the topic, I feel that all the non-vegetarian will change their stands.
