How to do sums on areas of triangle and circumference and area of circle pls give examples

Area of triangles is found by area = ½ (base × height) square units

Area of a circle is found by area=π r²

π which is pi equals 3.14 and r is radius then you square it. If you have diameter in your equation divide it by 2.

Circumference is found by 2(3.14)r-radius

Hope this helps

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.

i believe the answer is true
