WebThe first thing to do is find the circumference of our wheels; that will tell us how far our robot will go in one wheel revolution. Circumference is equal to π x D or: 3.14 x 2.5" = 7.85". We obviously can’t work with inches and centimeters in the same equation, so the easiest thing to do is convert the circumference from inches to ... WebSep 26, 2024 · Divide the circumference by 3.14 (pi): that gives you the diameter. Divide by 2: that gives you the radius. Square the radius, and multiply that by pi: that gives you the area.
