Question

find the diameter of a wheel whose criumference is 176cm

Answer 1

Answer :

The diameter of the wheel is 56 cm

Step-by-step explanation :

Circumference of a wheel = 2 π r

⇒ 2 π r = 176

⇒ 2 × 22 / 7 × r = 176

⇒ 44 / 7 × r = 176

⇒ 44 r = 1232

⇒ r = 1232 / 44

⇒ r = 28 cm.

We know that, diameter of a wheel is double of its radius.

Diameter = 2r

⇒ Diameter = 2 × 28

⇒ Diameter = 56 cm.

Hence, the diameter of the wheel is 56 cm.

Answer 2

Hence, the diameter of the wheel is 56 cm.
