Sure, let's solve for the radius of the circle step-by-step:
1. Understand the Problem:
- We are given the diameter of a circular tank which is [tex]\(3.15 \, \text{m}\)[/tex].
- We need to find the radius of the circle.
2. Formula to Use:
- The formula to calculate the radius ([tex]\(r\)[/tex]) from the diameter ([tex]\(d\)[/tex]) is:
[tex]\[
r = \frac{d}{2}
\][/tex]
3. Substitute the Diameter Value:
- Given [tex]\(d = 3.15 \, \text{m}\)[/tex]:
[tex]\[
r = \frac{3.15}{2}
\][/tex]
4. Calculate the Radius:
- Performing the division:
[tex]\[
r = 1.575 \, \text{m}
\][/tex]
5. Conclusion:
- The radius of the circular tank is [tex]\(1.575 \, \text{m}\)[/tex].
Thus, using the diameter of [tex]\(3.15 \, \text{m}\)[/tex], the radius of the circular tank is [tex]\(1.575 \, \text{m}\)[/tex].
