Represent the above data using a pie diagram.

Answer 1

Type	No. Students	Measure of central angle
Bicycle	$140$	$\frac{140}{360}\times {360}^o={140}^o$
Bus	$100$	$\frac{100}{360}\times {360}^o={100}^o$
Walk	$70$	$\frac{70}{360}\times {360}^o={70}^o$
Train	$40$	$\frac{40}{360}\times {360}^o={40}^o$
Car	$10$	$\frac{10}{360}\times {360}^o={10}^o$
Total	$360$	${360}^o$
