Answer 1

Answer:

2πr=16.5

2x22/7xr=16.5

44r=115.5

r=2.625

d=5.25

Answer 2

HOLA MATE HERE IS YOUR ANSWER.....

circumference \: of \: a \: circle \: is \: = 2\pi {r}circumferenceofacircleis=2πr

THE VALUE OF PIE BE 22/7

2 × 22/7× (R) = 16.5

R = (16.5 ×7) / 2 × 22

R = 115.5 / 44

R = 2.625 cm

DIAMETER = 2 × RADIUS

D = 2 × 2.625

=5.25 cm
