Answer:
The area is found to be 38.5
Step-by-step explanation:
The area of any circle is found by the formula as given below:
Area = π
Where we have, r = radius
Now in the question, we have diameter of the given wheel = 7 cm
Therefore the radius = 7 ÷ 2 = 3.5 cm
Area = π
⇒ Area = ×
⇒ Area = 38.5
Hence the area is 38.5
