The correct Answer is:
To find the radius of the floor of the conical tent, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Problem**: We are given the volume of a conical tent as \(1232 \, m^3\) and the area of the base floor as \(154 \, m^2\). We need to find the radius of the base of the cone. 2. **Formula for Area of Circle**: The area \(A\) of the base of the cone, which is circular, is given by the formula: \[ A = \pi r^2 \] where \(r\) is the radius of the base. 3. **Substituting the Given Area**: We know the area of the base is \(154 \, m^2\). Therefore, we can set up the equation: \[ \pi r^2 = 154 \] 4. **Using Approximate Value of \(\pi\)**: For calculations, we can use \(\pi \approx \frac{22}{7}\). Substituting this value into the equation gives: \[ \frac{22}{7} r^2 = 154 \] 5. **Eliminating the Fraction**: To eliminate the fraction, multiply both sides of the equation by \(7\): \[ 22 r^2 = 154 \times 7 \] 6. **Calculating \(154 \times 7\)**: Now, calculate \(154 \times 7\): \[ 154 \times 7 = 1078 \] So, we have: \[ 22 r^2 = 1078 \] 7. **Isolating \(r^2\)**: Next, divide both sides by \(22\) to solve for \(r^2\): \[ r^2 = \frac{1078}{22} \] 8. **Calculating \(\frac{1078}{22}\)**: Now, perform the division: \[ r^2 = 49 \] 9. **Finding the Radius \(r\)**: Finally, take the square root of both sides to find \(r\): \[ r = \sqrt{49} = 7 \] 10. **Final Answer**: Therefore, the radius of the floor of the conical tent is: \[ r = 7 \, m \]
