The distance around the equator of Saturn is about 378,675 km. What is the equatorial diameter of Saturn? Use pi = 3.14.
A) 241,209
B) 241,194
C) 120,584
D) 120,597
I think it is [D] but I'm not sure.

• Geometry! -

d is correct

• Geometry! -

C = pi * d

378,675 = 3.14d

378,675/3.14 = d

120,597 = d

You're right.

• Geometry! -

d pi = 378,675 Divide both sides by pi

d = 378,675 / pi

d = 378,675 / 3.14

d = 120.597,133 km
