Answer:

hey friend your answer is

Step-by-step explanation:

d= 7cm

r= 7/2 = 3.5cm

area = πr²

22/7 × 3.5²

22/7 × 12.25

22 × 1.75

38.5 cm².

hope it helps you

Answer:

The area is found to be 38.5cm^{2}

Step-by-step explanation:

The area of any circle is found by the formula as given below:

Area = π r^{2}

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 (3.5)^{2}

⇒ Area = \frac{22}{7} × (3.5)^{2}

⇒ Area = 38.5 cm^{2}

Hence the area is 38.5cm^{2}
