Answer 1

Answer:

22cm

Step-by-step explanation:

the circumference is 2pia r

22/7*7=22cm

Answer 2

Step-by-step explanation:

☆Question☆

The diameter of wheel is 7 m, find its Circumference.

☆Answer☆

1. The diameter of wheel is 7 m, find its Circumference

• a. 33 cm
• b. 44 cm
• c. 25 cm
• d. 22 cm ✔

☆Given☆

• The diameter of wheel is 7m

$\sf \bf \: So, \: the \: radius \: of \: the \: wheel \: will \: be \: \dfrac{7}{2}m \: i.e. \: 3.5m$

☆Formula☆

$\underline{ \boxed{ \sf{ \pink{we \: know \: that \: the \: circumference \: of \: wheel\: = \bf \: 2\pi \: r}}}}$

Now by substituting the value , we get

☆Solution☆

$\rightarrow \: \sf \: circumference \: of \: the \: wheel \: = \: 2 \times \dfrac{22}{7} \times 3.5$

$\rightarrow \: \sf \: circumference \: of \: the \: wheel \: = \: 2 \times \dfrac{22}{7} \times \dfrac{35}{10}$

$\rightarrow \: \sf \: circumference \: of \: the \: wheel \: = 22 \: cm$

•°• We got that the Circumference of the wheel is 22 cm
