Answer 1

Answer:

r≈9.02

C Circumference

56.7

Answer 2

Answer:

circumference of circle = 56.7 cm

(We know that circumference of circle =

$2\pi r \: or \: 2d$

Therefore,

$\: \: \: \: \: \: \: \: \: \pi d = 56.7 \\ \\ = \pi d = 56.7 \\ = 22 \div 7 \times d = 56.7 \\ = \: 22 \times d = 56.7 \times 7 \\ = 22 \times d = 396.9 \\ = d = 396.9 \div 22 \\ = 18.0409090909$
