A)
Obw= 2*3,14*2 =12,56cm
Obw = 6,28*4 = 25,12m
Obw = 6,28*0,3 = 1,884cm
Obw = 6,28*10 = 62,8km
b)
Obw = 6,28*1 = 6,28cm
Obw = 6,28 * 1,5 = 9,42m
Obw = 6,28 *0,2 = 1,256cm
Obw = 6,28 *100 = 628m
c)
6,28*r = 10m
r≈1,59m
6,28*r = 1m
r≈0,159
6,28*r = 628mm
r=100mm
6,28*r = 3,5cm
r≈ 0,557cm

The Hertzspring-Russel Diagram or HR-Diagram is used to study the evolution of stars. It plots stars depending on the temperature against luminosity. Stars go through different changes depending on its mass at the beginning. These changes occurs in stages and each stage is marked by a change in temperature and luminosity.
