To calculate the area of a circle, you can use the formula:
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius of the circle.
Given:
- Radius \( r = 75 \) mm
- \( \pi \approx 3.14 \)
Substituting the values into the formula:
\[
\text{Area} = 3.14 \times (75)^2
\]
Now calculate \( (75)^2 \):
\[
(75)^2 = 5625
\]
Now substitute this back into the area formula:
\[
\text{Area} = 3.14 \times 5625
\]
Now calculate \( 3.14 \times 5625 \):
\[
3.14 \times 5625 \approx 17678.125
\]
Now to round to the tenths place:
\[
17678.1
\]
Therefore, the approximate area of the circle is:
\[
\boxed{17678.1 \, \text{mm}^2}
\]
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius of the circle.
Given:
- Radius \( r = 75 \) mm
- \( \pi \approx 3.14 \)
Substituting the values into the formula:
\[
\text{Area} = 3.14 \times (75)^2
\]
Now calculate \( (75)^2 \):
\[
(75)^2 = 5625
\]
Now substitute this back into the area formula:
\[
\text{Area} = 3.14 \times 5625
\]
Now calculate \( 3.14 \times 5625 \):
\[
3.14 \times 5625 \approx 17678.125
\]
Now to round to the tenths place:
\[
17678.1
\]
Therefore, the approximate area of the circle is:
\[
\boxed{17678.1 \, \text{mm}^2}
\]
