Answer:
19.74 inches
Explanation:
Given as
Circumference of wheel = 62 inches
AS we know that Circumference (C) = 2×
×R
where R is Radius of circle
so, C = 2 × 3.14 × R
or, 62 = 2 × 3.14 × R
or 62 = 6.28 × R
so, Radius (R) =

R = 9.872
Now Diameter = 2 × Radius
so, D = 2 × 9.872
Diameter = 19.74 inches Answer
