Question

Hello friends...!

A bicycle makes 500 revolution in moving 11km. Find the diameter of the wheel?

please dont spam.........!

Answer 1

$\textbf{\huge{ANSWER:}}$

Given:

Bicycle makes 500 revolutions in moving 11 Km

1 Km = 100000 cm

11 km = 1100000 cm

Distance covered in 1 revolution = $\frac{1100000}{500}$

=》 Distance = 2200 cm

Circumference of a circle = Distance covered in 1 revolution

=》 $2 \pi r = 2200$

=》 $2 \times \frac{22}{7} r = 2200$

=》 $r = \frac{2200\times 7}{22 \times 2}$

=》 r = 350 cm

Diameter = 2r

=》 D = 2 × 350

=》 $\textbf{D = 700 cm}$

Hope it Helps!! :)

◀ HEY THERE!◀

◀ Question: ◀

↪ A bicycle makes 500 revolution in moving 11km. Find the diameter of the wheel?

◀ Method of Solution: ◀

Distance covered by the wheel in 1 Revolution ⇒ 11×1000×100 / 500

⇒11×1000×100/500

⇒ 11× 1000/5

⇒ 11×200

⇒2200 cm

•°• Circumference of the wheels = 22 cm.

→ Let the diameter of circle be d cm.

→ Then, Circumference of Circle = 2πr

⇒. Circumference = 2π×(d/2)

•°• Circumference of Circle = πd

→ According to the Question's Statement!→

⇒ 2200 = 22/7×d

⇒ 2200×7=22d

⇒ 15400 = 22d

⇒ •°• d = 700 cm

◀ Hence, ↪ diameter of the wheel is 700 cm→◀
