Question

find the difference between the perimeter of two circular plates , if one has a radius of 16.8cm and the other has a diameter of 16.8cm​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of first plate 2πr= (2)(3.14)(16.8)= 105.504 cm

Perimeter of second plate

d= 16.8 cm/2= 8.4cm

2πr= (2)(3.14)(8.4)= 52.752 cm

Therefore,

Difference= 2πr1-2πr2= 105.504 cm- 52.752 cm= 52.752 cm
