Question

If the wheel of a bicycle makes 1000 revolutions in
travelling 2.2 km, what is its radius?
A. 37.66 cm,
B. 38.56 cm
C. 35 cm
D. 36 cm​

Answer 1

Answer:

Option C

Step-by-step explanation:

220000 = 1000 × 2 π R

220000 = 1000 × 2 π R R = 110/π === 110/22 × 7 = 35 cm

Answer 2

c. 35 cm

220000 = 1000 × 2πR

220000 = 1000 × 2πR

= 110 /π

110/22 × 7 = 35cm
