Question

Find the circumference of the wheel of Ashok’s cycle whose diameter is 21 cm.

Answer 1

Answer:

65.97

Step-by-step explanation:

first we use the formula c = 2πr

then we solve by filling the values as diameter or d is given 21 and we know that π = 22/7 and radius is d/2 i.e.21/2

66. cm

Answer 2

Step-by-step explanation:

radius = 21/2

circumference. = 2πr

= 2*22/7*21/2

= 66cm
