Question

22
Find the circumference of the circles with the following radius: (Take \pi =
$\frac{22}{7}$
(a) 14cm
(b) 28 mm
(c) 21 cm
(a) 14 cm​

Answer 1

Answer:

(a)14cm

Circumference = $2\pi r$ = 2×  22/7 × 14 = 88cm

(b)28 mm  

Circumference = $2\pi r$ = 2 × 22/7 ×22mm = 968/7mm

(c) 21 cm

circumference = $2\pi r$ = 2 × 22/7 × 21cm = 132cm

(a) 14 cm

circumference = $2\pi r$ = 2 × 22/7 × 14cm = 88cm
