What is the area of a circle with radius 8? (Use π ≈ 3.14)

• A. 200.96
• B. 202.5
• C. 195.8
• D. 210.6

Answer: (A)

To find the area of a circle, the formula used is \( A = \pi r^2 \), where \( A \) represents the area and \( r \) is the radius of the circle. In this case, the radius is given as 8. First, we square the radius: \[ r^2 = 8^2 = 64. \] Next, we multiply this result by \( \pi \): \[ A = \pi \times 64. \] Using the approximation \( \pi \approx 3.14 \): \[ A \approx 3.14 \times 64 = 200.96. \] Thus, the area of the circle is approximately 200.96 square units. This calculation confirms that the correct choice is indeed the first option, which states that the area is 200.96.

To find the area of a circle, the formula used is ( A = \pi r^2 ), where ( A ) represents the area and ( r ) is the radius of the circle. In this case, the radius is given as 8.

First, we square the radius:

[

r^2 = 8^2 = 64.

]

Next, we multiply this result by ( \pi ):

[

A = \pi \times 64.

]

Using the approximation ( \pi \approx 3.14 ):

[

A \approx 3.14 \times 64 = 200.96.

]

Thus, the area of the circle is approximately 200.96 square units. This calculation confirms that the correct choice is indeed the first option, which states that the area is 200.96.
