Question

An object from A to B in a circular path of radius 7 m . What is the distance travelled? what is the displacement?

Answer 1

$\tt\pink{Displacement=Diameter}$

$\tt\blue{ = 2 \times radius}$

$\tt\blue{ = 2×7=14 \: m}$

$\tt\pink{Distance \: travelled = \frac{1}{2}\times Circumference}$

$\tt\blue{ = \frac{1}{2} \times 2 \times π \times r}$

$\tt\blue{ = \frac{1}{2} \times 2 \times \frac{22}{7} \times 7}$

$\tt\blue{ = 22m}$

Answer 2

$\small\bold{Displacement = Diameter } \: \\ \small\bold\red{2 × radius = 2 × 7= 14 m} \\ \small\bold\purple{ Distance \: traveled = × circumference} \\ \\ ⟹ \: \frac{1}{2}×2×\pi × \: r \\ ⟹\frac{1}{2} \times 2 \times \frac{22}{7} \times 7 \\ \ = 22$
