Question

How many times does a wheel of radius 35 cm rotate to go 330 m? (pai = 22/7)

Answer 1

Answer:

here,

as one rotation means one circumference so first take circumference by the formula 2pi r

which is 220m.the wheel hast to go 330m .divide 330 by 220 which is 1.5

Step-by-step explanation:

thus the wheel has to rotate 1.5m

Answer 2

Answer:

Wheel will rotate 150 times.

Question :- How many times does a wheel of radius 35 cm rotate to go 330 m?

To Find :- No.of times wheel will rotate.

First we have to find the circumference of wheel.

Circumference =

2 \times \pi \times r2×π×r

Circumference =

2 \times \frac{22}{7} \times 352×

7

22

×35

Circumference = 2 × 22 × 5

Circumference = 44 × 5

Circumference = 220

Now we have to convert 330m to cm.

1m = 100cm

330m = ?cm

330 × 100 = 33000cm

Now we will divide distance by the circumference of wheel.

= 33000 \div 220=33000÷220

= 150=150
