The correct Answer is:
To find the volume of a cylinder given the circumference of its base and its height, we can follow these steps: ### Step 1: Understand the relationship between circumference and radius The circumference \( C \) of a cylinder is given by the formula: \[ C = 2\pi r \] where \( r \) is the radius and \( \pi \) is a constant approximately equal to \( \frac{22}{7} \). ### Step 2: Substitute the given circumference into the formula We know that the circumference is 132 cm, so we can set up the equation: \[ 2\pi r = 132 \] ### Step 3: Substitute the value of \( \pi \) Using \( \pi = \frac{22}{7} \), we can rewrite the equation: \[ 2 \times \frac{22}{7} \times r = 132 \] ### Step 4: Simplify the equation to solve for \( r \) Multiplying both sides by 7 to eliminate the fraction: \[ 2 \times 22 \times r = 132 \times 7 \] \[ 44r = 924 \] ### Step 5: Solve for \( r \) Now, divide both sides by 44: \[ r = \frac{924}{44} \] \[ r = 21 \text{ cm} \] ### Step 6: Use the radius to find the volume of the cylinder The volume \( V \) of a cylinder is given by the formula: \[ V = \pi r^2 h \] where \( h \) is the height of the cylinder. ### Step 7: Substitute the values of \( r \) and \( h \) Given that the height \( h = 25 \) cm, we substitute \( r = 21 \) cm into the volume formula: \[ V = \frac{22}{7} \times (21)^2 \times 25 \] ### Step 8: Calculate \( (21)^2 \) Calculating \( (21)^2 \): \[ (21)^2 = 441 \] ### Step 9: Substitute back into the volume formula Now substitute \( 441 \) into the volume formula: \[ V = \frac{22}{7} \times 441 \times 25 \] ### Step 10: Simplify the expression First, calculate \( \frac{22 \times 441}{7} \): \[ \frac{22 \times 441}{7} = 22 \times 63 = 1386 \] Now multiply by 25: \[ V = 1386 \times 25 \] ### Step 11: Calculate the final volume Calculating \( 1386 \times 25 \): \[ V = 34650 \text{ cm}^3 \] ### Final Answer The volume of the cylinder is: \[ \boxed{34650 \text{ cm}^3} \]
