Question

The diameter of a wheel is 56 cm. The total distance covered by it in 11 revolutions

is​

Answer 1

Answer:

1936

Step-by-step explanation:

circumference=2πr=176

total distance=11×176=1936

Answer 2

Answer:

PERIMETER OF CIRCLE = 2πR

( HERE RADIUS = ½ × DIAMETER = ½ × 56 = 28cm )

PERIMETER = 2 × 22/7 × 28

PERIMETER = 22 × 2 × 4 = 44 × 4 = 176cm

NOW ,

TOTAL REVOLUTIONS = 11

SO DISTANCE COVERED = TOTAL REVOLUTIONS × PERIMETER

DISTANCE COVERED = 176 × 11 = 1936cm

SO DISTANCE COVERED IN 11 REVOLUTIONS IS 1936cm OR 19.36 meters
