Question

type your answer in the blank. find the area of the circle in square meters. round your answer to the nearest whole number. the area is about square meters.

Explanation:

Step1: Find the radius

The diameter of the circle is 8.4 m, so the radius \( r = \frac{8.4}{2} = 4.2 \) m.

Step2: Calculate the area

The formula for the area of a circle is \( A = \pi r^2 \). Substitute \( r = 4.2 \) into the formula: \( A = \pi \times (4.2)^2 \approx 3.1416 \times 17.64 \approx 55.4176 \).

Step3: Round to the nearest whole number

Rounding 55.4176 to the nearest whole number gives 55.

Answer:

55
