how would i solve this ??
A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk mark returned to the same position. The team then measured the distance the wheel had rolled and found it to be 35 cm. To the nearest tenth, what is the area of the wheel?

97.5 cm2
195.1 cm2
27.5 cm2
390.1 cm2

35 is your circumference.  From that, you can get the radius from:

Circumference = (2)(pi)(r)

Then,   Area = (pi)(r^2)
