Question

A wheel has a radius of 15 cm. Approximately how far does it travel in 4 revolutions?

A.
188.4 cm

B.
94.2 cm

C.
376.8 cm

D.
47.1 cm

Answer 1

find the circumference and multiply it by 4

Answer 2

wait is it d ?

Answer 3

4 x (2 pi R)

Answer 4

nope

Answer 5

376.8 cm = pi x d x 4 = pi x (15x2) x 4

Answer 6

yes well close enough... idk but i keep getting 376.99

Answer 7

@elementwielder is C

Answer 8

yes

Answer 9

if it has a radius of 15, multiply that by 2 to get 30, which is your diameter. Circumference = diameter*pi = 30Pi = 94.2. In four revolution (94.2*4) it would have traveled 376.8
