Question

The radius of a circle is 75 mm. What is the approximate area of the circle? Write your answer to the tenths place. Use 3.14 for π .(1 point)..

Answer 1

wrong

Answer 2

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 \( r = 75 \) mm and using \( \pi \approx 3.14 \), we can substitute the values into the formula:

\[
\text{Area} \approx 3.14 \times (75)^2
\]

First, calculate \( 75^2 \):

\[
75^2 = 5625
\]

Now, substitute this value back into the area formula:

\[
\text{Area} \approx 3.14 \times 5625
\]

Now, perform the multiplication:

\[
\text{Area} \approx 17647.5
\]

Thus, the approximate area of the circle is:

\[
\text{Area} \approx 17647.5 \text{ mm}^2
\]

Therefore, the area of the circle rounded to the tenths place is **17647.5 mm²**.
