Question

A bicycle tire has a diameter of 62 cm.
What is the distance the bicycle tire travels in 10 revolutions?
Round your answer to the nearest cm.

Answer 1

so radius would be 31

so circumference would be

$2*π*r$
$2*22/7*31$
$=194.8cm$
$(on \:round \:figuring \:the \:circumference)$
$=195cm$
$since \:it \:made \:10 \:rounds$
$=195*10=1950cm$

Answer 2

Answer:

The answer to this specific question from Khan academy is 1947 cm.

Step-by-step explanation:

c = πd

c = π (62)

c = 62 π

10 x 62 π = 620 π

620 π ≈ 620 × 3.14

≈ 1946.8

≈ 1947 cm
