The clock face in a famous clock tower has a radius of about 4

Question

meters. What is the area of the clock face to the nearest square meter? Use 3.14
as an approximation for pi
.

Answer 1

To find the area of a circle, you can use the formula:

\[ \text{Area} = \pi r^2 \]

where \( r \) is the radius of the circle.

Given that the radius \( r \) of the clock face is 4 meters, we can substitute this value into the formula along with \( \pi \approx 3.14 \):

\[ \text{Area} = 3.14 \times (4)^2 \] \[ = 3.14 \times 16 \] \[ = 50.24 \]

Rounding this to the nearest square meter, the area of the clock face is:

\[ \text{Area} \approx 50 \text{ square meters} \]
