Answer 2

$\sf \: Circumference \: of \: circle = 2\pi r$

$\bf = > 2\pi r = 5.28 \\ \bf = > r = \frac{5.28 \times 7}{2 \times 22} = \frac{528 \times 7}{100 \times 2 \times 22} \\ \\ \bf = > r = \frac{264 \times 7}{22 \times 100} = \frac{12 \times 7}{100} \\ \\ \bf= > r = 0.84 \: m \\ \bf= > r = { \red{84 \: cm}}$
