Answer 1

$\huge\mathbf\red{Answer}$

Circumference of circle=2πr

a]

$2 \times \frac{22}{7} \times 14$

$2 \times 22 \times 2$

$88cm$

b]

$2 \times \frac{22}{7} \times 28$

$2 \times 22 \times 4$

$166mm$

Answer 2

Answer:

a.88cm

b.196mm

$circumference \: of \: circle = 2\pi \: r \\ a. \: \: \: \: 14 \times 22 \7 \times 2 = 2 \times 2 \times 22 = 88 \\ b. \: \: \: \: 28 \times 22 \7 \times 2 = 4 \times 22 \times 2 = 196$
