Answer:

628 inches

Explanation:

Circumference = 3.14*d > 3.14 x 20 = 62.8

t = 62.8 x 10

t = 628 inches

Answer:

200π

Explanation:

The circumference of a circle equation is C = 2πr

r is the radius and in this case is 10

So the circumference is 20π, and if the wheel made 10 complete rotations, you just multiply the circumference by 10 to get 200π

Hope this helped :)
