Answer:

Option C. 154 cm²

Step-by-step explanation:

From the question given above, the following data were obtained:

Pi (π) = 22/7

Diameter (d) = 14 cm

Area (A) =?

Next, we shall determine the radius of the circle. This can be obtained as follow:

Diameter (d) = 14 cm

Radius (r) =?

r = d/2

r = 14/2

r = 7 cm

Finally, we shall determine the area of the circle as illustrated below:

Pi (π) = 22/7

Radius (r) = 7 cm

Area (A) =?

The area of a circle can be obtained by using the following formula:

A = πr²

A = 22/7 × 7²

A = 22/7 × 7 × 7

A = 22 × 7

A = 154 cm²

Thus, the area of the circle is 154 cm²
